Wage Structure of the Machine-Tool Accessories
Industry, January 19451
Sum m ary

In January 1945, the average plant worker in the machine-tool acces­
sories industry earned $1.19 an hour, excluding premium pay for over­
time and night-shift work. Earnings of individual workers varied
from less than 50 cents to more than $2.30; 1 out of every 28 workers
received less than 65 cents an hour.
Average hourly earnings were distinctly higher in tool and die
jobbing shops than in establishments engaged in the manufacture of
machine-tool accessories on a relatively large-scale production basis,
the averages for the two branches of the industry being $1.28 and $1.08,
respectively. This variation reflects differences in occupational com­
position in the two branches of the industry as well as differences in
pay for some of the key jobs.
Women plant workers in production shops averaged 86 cents an
hour and men $1.14; in tool and die jobbing shops the corresponding
figures were 82 cents and $1.32. In both branches of the industry, a
comparison based on similar occupations given identical weights
showed a difference in pay of about one-seventh in favor of men.
Of the three most important regions in the industry, the Great
Lakes region had the highest levels of pay in both types of shops.
New England was the lowest in the jobbing branch; in production
shops New England and Middle Atlantic were equally low. In
general, average levels of pay were found to be higher in large than
in small communities and in union as compared with nonunion plants.
In production shops, where the incentive method of pay was relatively
important, earnings of time workers were generally below those of
incentive workers in the same job. No consistent relationship between
level of pay and size of establishment was apparent.
Straight-time average hourly earnings of workers engaged in the
manufacture of machine-tool accessories were augmented by premium
overtime pay, shift differentials, and other supplementary wage bene­
fits. Practically all establishments had a scheduled workweek of at
least 48 hours in January 1945, with premium overtime pay for hours
in excess of 40. About a fourth of the production-shop workers and
15 percent of the jobbing-shop employees were on late shifts; almost
all of these workers in production shops received extra pay, while

premium pay was provided by about three-fourths of the jobbing
shops operating late shifts.
Nonproduction bonuses for plant workers were reported by about
three-fifths of the production shops and half of the jobbing shops.
Formal vacation plans for employees with a year’s service were com­
mon in this industry in January 1945, but formal sick-leave plans were
rare for plant workers and relatively uncommon even for the office
staff. Insurance or pension plans were reported quite frequently in
the industry, although they were less prevalent than vacation benefits.
Characteristics o f the Industry

Machine-tool accessories are essential in the production of prac­
tically all metal products, including machinery, automobiles, air­
planes, and other transportation equipment as well as ordnance.
Accordingly, they played a key role in wartime production; employ­
ment in their manufacture increased about 300 percent between 1939
and December 1942, the wartime peak in the industry. This ex­
pansion may be traced in part to the fact that substitution of one type
of machine-tool accessory for another permitted conversion of some
metalworking machines from peacetime to wartime production. In
addition, the high level of metalworking activity carried with it a
large demand for replacements for accessories, many of which wear
out rapidly with use. For the same reasons, the machine-tool ac­
cessories industry, despite its relatively small employment (approxi­
mately 130,000 in January 1945), is of strategic importance in the
reconversion of metalworking machinery to peacetime production
and in the maintenance of peacetime output. These considerations
led the Bureau of Labor Statistics to include the industry in its In­
dustry Wage Studies program for 1945.
As defined for purposes of the present study, the machine-tool
accessories industry includes establishments primarily engaged in the
manufacture of attachments and accessories for machine tools and
other metalworking machinery, small power-driven cutting and shap­
ing tools, and precision measuring tools. Among the products of
these establishments are cutting tools (including drills, tool bits for
lathes, milling cutters, and reamers); machine-tool attachments, such
as collars and arbors for holding cutting tools; attachments for other
metalworking machinery, such as dies for die-casting and drop­
forging machines, and forming and shaping tools for sheet-metal
machines; jigs, fixtures, and other attachments for holding work that
is being machined or otherwise worked; and such precision measuring
instruments as micrometers and gages used in measurement of metal­
working products.2
Two major types of establishments may be distinguished in the
industry: Those that manufacture more or less standardized acces­
sories normally produced in large quantities to stock; and shops that
are engaged primarily in the production of nonstandard machine-tool
accessories on a jobbing basis to fill special orders. For convenience,
this study refers to the former as production shops and the latter as
jobbing shops. Production shops are engaged mainly in the manu­

(issued by the Bureau of the Budget), Code No. 3543.

facture of precision measuring instruments, cutting tools, and collars
and arbors for holding such tools. Jobbing shops produce a larger
proportion of the dies for forging and die-casting machines, shaping
tools for sheet-metal machines, and jigs and fixtures, since the latter
types of accessories frequently must be made to fit individual speci­
fications. Partly because of such product differences but mainly
because of differences in size, production methods, and occupational
structure, wage rates and related practices in each type of shop are
discussed separately in this article.
Scope o f Study

The data summarized here cover production shops with eight or
more employees; for the tool and die jobbing branch, in which very
small establishments are common, shops with as few as five workers
were studied.3 The Bureau’s survey included 156 production estab­
lishments with 32,600 workers, and 623 tool and die jobbing shops
with 26,400 workers. This represented over two-fifths of all produc­
tion establishments above the minimum size studied, employing
about half of the employees in this branch of the industry, and about
a third of all tool and die jobbing shops with five or more workers.
About two-fifths of all workers in jobbing shops were covered. Some
of the special analyses were based on smaller samples.
The establishments studied were selected to provide representation
of the most important factors affecting wage rates. Data for most
establishments were taken from a January 1945 pay roll, although in
some cases an April period was utilized.
The Labor Force

Because the manufacture of machine-tool accessories involves a
large amount of precision.work, both branches of the industry employ
a relatively high proportion of skilled workers. However, in jobbing
shops, where the work consists of a variety of specialized jobs, the
proportion of skilled workers is higher than in production shops. In
the latter branch greater standardization of output has resulted in
employment of a large number of workers per plant, permitted a finer
division of labor, and limited the variety of tasks performed by indi­
vidual workers.
Occupational groups.— The differences between the two types of
establishments appear most clearly in the proportion of tool and die
makers employed. In January 1945 these workers, who perform all or
most of the operations necessary to the manufacture of finished tools or
dies, constituted a fourth of the plant workers in tool and die jobbing
shops (23 percent of all workers) as contrasted with about 3 percent of
the workers in production shops.4
Jobbing shops also employed a higher proportion of production
machinists and miscellaneous machine-tool operators who operate a
* Despite the relatively high level of employment in January 1945, at least 4 out of every 5 jobbing shops
employed fewer than 50 workers and many employed fewer than 10 workers. Although a large number of
plants turning out more or less standardized lines of machine-tool accessories also employed fewer than 50
workers, the greater number of such production establishments had more than 50 employees. Thus, whereas
only 1 out of 60 tool and die jobbing shops had more than 250 employees, about 1 out of 5 production plants
employed 250 or more workers and about 1 out of 10 employed over 500 workers.
4 A related difference is the higher proportion of apprentices found in jobbing shops; they accounted for
only 0.2 of 1 percent of the workers in production shops, compared with 4.5 percent in jobbing shops.




4
variety of machines instead of specializing on work of a single type of
machine. Together these two groups accounted for less than 1 percent
of the labor force in production shops, and about 7 percent in jobbing
shops; in the latter, production machinists alone constituted more
than 3 percent of the total employment. Production shops used com­
paratively more specialized machine-tool operators (notably grinding
and milling-machine operators) and assemblers to perform parts of
the work carried on by all-round tool and die makers, machinists, and
miscellaneous machine-tool operators. Moreover, within these special­
ized occupational groups, larger proportions of the workers in jobbing
shops were skilled and performed a greater variety of tasks involving
less division of labor than was typical of production establishments.
Tool and die makers, machinists, machine-tool operators, and assem­
blers together comprised the greater part of the processing workers in
the two branches of the industry. Both branches also employed
workers in other metalworking processes such as stamping and forming,
heat treating, polishing, and buffing. Some large production estab­
lishments also find it advantageous, because of their size and more
standardized work, to make their own castings or forgings. Hence
they employ patternmakers, molders, drop-hammer operators, and
other forging and foundry workers. Even in these shops, however,
aggregate employment in the latter processes in January 1945 was
small. Very few tool and die jobbing shops wrere found to be carrying
on foundry and forging operations.
Differences in the composition of the labor force between the two
types of shops were also evidenced in the proportions of workers em­
ployed directly on processing work. Because production shops manu­
facture standard items in relatively large quantities, it was to be
expected that a comparatively smaller part of their labor force as
compared with the specialized jobbing shops, would be found in process­
ing. Altogether, about half of the workers in production shops and
between two-thirds and three-fourths of those in tool and die jobbing
shops were employed directly in processing operations. These differ­
ences are related in part to size of plant. Workers engaged primarily
in packing and handling material, in inspection, in maintenance of
equipment, in office work, and in other nonprocessing functions were
relatively more numerous in production than in jobbing shops. In
the latter establishments, these operations were frequently per­
formed by processing workers as part of their general work or were
actually less important in terms of total man-hours required.
Women workers.— In January 1945 women accounted for about
a fifth of the plant workers in the production branch of the industry;
the small size of many of the units produced and the relatively high
degree of division and standardization of work facilitated their em­
ployment. Conversely, the greater variety of work and the resulting
greater need for persons with longer periods of training and experience
limited the plant job opportunities for women in jobbing shops. At
the time of the survey, only about 1 out of every 12 plant workers
in tool and die jobbing shops was a woman. In both branches most
of the women plant workers were employed as class C operators of
machine tools (primarily on drilling, milling, and grinding machines)
and as class C inspectors and assemblers.




5
Unionization.— In January 1945 about two-fifths of the production
establishments, employing about 70 percent of the workers in this
branch of the industry, were operating under union agreements cover­
ing at least half of the employees. Unionization was less prevalent
in the relatively small tool and die jobbing shops; only about a fourth
of these establishments, with about two-fifths of the workers, were
unionized.
W age Structure

The wage structure of machine-tool accessories establishments is
summarized in this article in terms of hourly rates (straight-time
average hourly earnings in the case of incentive workers) excluding
premium pay for overtime and late-shift work. Incentive earnings
are included in the data but nonincentive bonuses, such as Christmas
and profit-sharing bonuses, are excluded. Cost-of-living bonuses are
considered as part of the worker’s regular pay.
Occupational averages are presented only for key plant and office
jobs; no attempt has been made to present separate information for
all occupations in the industry. However, all plant workers rather
than only those in key occupations were included in the general
averages and frequency distributions; administrative, executive,
professional, and office employees were excluded from these averages.
The wages of inexperienced beginners, apprentices and handicapped
workers were omitted from the wage data for specific occupational
groups but were included in the general averages and distributions.
The number of workers reported represents the approximate em­
ployment on all shifts in all establishments in the industry (excluding
those below the minimum size covered by the study) rather than the
employment in the establishments actually studied.
UNITED STATES AS A WHOLE
Average H ourly Earnings

In January 1945, straight-time hourly earnings of plant workers
in the machine-tool accessories industry averaged $1.19 (table 1).
There was a relatively wide spread in earnings among individual
workers within the industry, from less than 50 cents to over $2.30 an
hour. Half of the workers received between 70 cents and $1.25.
About 1 out of every 28 workers received less than 65 cents an hour
in January 1945.
Average hourly earnings were notably higher in jobbing than in
production shops, the respective averages being $1.28 and $1.08.
This difference reflects, in part, dissimilarities in the skill composition
of the labor force and, in part, the higher rates of pay in jobbing shops
for some occupations filled by large numbers of workers.
A graphic comparison of the distribution of average hourly earnings
in the two branches of the industry is provided in chart 1. It in­
dicates a somewhat narrower concentration of earnings in the produc­
tion branch of the industry than in tool and die jobbing shops; earnings
of over half of the workers in the former fell within a 50-cent range
(from 70 cents to $1.20) whereas the range for half of the tool and die
jobbing-shop workers was 70 cents (from 70 cents to $1.40). The
greater dispersion of earnings in jobbing shops appears to be related to




6
the higher proportion of skilled workers and wider regional differences
in rates in the latter branch of the industry.
About a fourth of the workers in production shops earned between 90
cents and $1.10 an hour, whereas about the same proportion of jobbingshop workers averaged between $1.50 and $1.80. This concentration
of rates between $1.50 and $1.80 in jobbing shops reflected primarily
the earnings of tool and die makers. Despite the generally higher
level of earnings in tool and die jobbing shops, the proportion of




7
workers receiving less than 65 cents was about the same in both
branches of the industry.

Occupational W age Rates

National levels of pay for a group of selected occupations in both
branches of the machine-tool accessory industry arc presented in
table 2. This table provides an interesting comparison of wage levels
in the two types of shops and indicates that the average rates of pay
provided for some of the most important skilled jobs in the industry
were higher in tool and die jobbing shops than in production shops.
Thus, tool and die makers and class A grinding-machine operators
averaged $1.55 in jobbing shops compared with $1.42 in production
shops; class A milling-machine operators averaged $1.41 and $1.34
respectively, in the two branches of the industry. This differential
may be related at least in part to the greater versatility of work in
tool and die jobbing shops. The reverse wage relationship was
reported for some of the less-skilled jobs in which more workers
were paid on an incentive basis in production than in jobbing shops.
A comparison limited to time workers in the less-skilled jobs indicates,
on the whole, a smaller difference in pay between the two branches of
the industry than appears when incentive workers are included.

1 Excluding premium pay for overtime and night work.
2 Insufficient number of workers to justify presentation of an average.
Variation in Wages b y Sex

Straight-time average hourly earnings of men plant workers in
machine-tool accessories production shops averaged $1.14 in January
1945 as contrasted with 86 cents for women plant workers. For tool
and die jobbing shops the corresponding averages were $1.32 and 82
cents. Half of the women in both branches of the industry earned
between 60 cents and 85 cents, whereas half of the men in production
shops earned between 85 cents and $1.30 an hour and half of those in
jobbing shops earned between $1.25 and $1.90.
These variations in general averages reflect not corresponding
differences in pay for comparable work, but rather the fact that
women were employed in greater degree than men in the less-skilled
operations. Similarly, the wider spread between the averages for
men and women in tool and die jobbing shops than in production
shops does not imply necessarily a corresponding difference for
workers in identical jobs; it is accounted for primarily by greater
differences in the type of jobs performed by men and women employed
in jobbing shops.
A special analysis, removing the influence of differences in the
occupations filled by men and women, indicated that men's earnings




10
averaged about one-seventh more than those of women. Considering
all establishments as a group, earnings of men, though not necessarily
for identical work in identical establishments, appeared to be sig­
nificantly above those for women. An analysis of rates for men and
women paid on a time basis revealed an average difference of less
than 5 percent in the production branch of the industry; in jobbing
shops, incentive payment was uncommon.
REGIONAL VARIATIONS IN W AGE LEVELS 6

Both in production and jobbing shops, levels of pay were distinctly
higher in the Great Lakes region than in the other important regions
(New England and the Middle Atlantic States) in the industry.
This variation was observed not only in average hourly earnings for
all plant occupations combined but also in individual occupational
wage rates and in minimum entrance and job rates. In production
shops, earnings in the Pacific Coast region exceeded those in the Great
Lakes region, but the former employed only a small number of workers
in this branch of the industry.
Average hourly earnings in the three important regions in the
production branch of the industry differed by 14 percent, the average
being $1.14 in the Great Lakes region and $1.00 in both New England
and the Middle Atlantic States. In jobbing shops, rates in the
Great Lakes region were about 35 percent above those in New Eng­
land, which also had distinctly lower levels of pay than the Middle
Atlantic region. Still lower were rates in tool and die jobbing shops
in the Border States and Southeast, where one-eighth and one-seventh,
respectively, of the workers received less than 65 cents an hour, coifipared with 1.6 percent in the Great Lakes region; production shops
were practically nonexistent in the two former regions.
In view of the importance of tool and die makers in jobbing shops,
the interregional variation in rates in such shops for this occupation
is of special interest. The rates for tool and die makers varied from
an average of $1.29 in the New England and Border States to $1.62
in the Great Lakes and Pacific regions.
VARIATION OF OCCUPATIONAL W AGE LEVELS W ITH SIZE OF ESTABLISHMENT,
SIZE OF CITY, UNIONIZATION, AND METHOD OF W AGE PAYMENT

An examination of the data drawn from January 1945 pay rolls
indicates that in both branches of the industry there was no consistent
variation in pay levels with size of establishment. Levels of pay,
however, tended to be higher in union than in nonunion plants and
in large rather than in small communities, although there were excep­
tions in some jobs. In production shops, where incentive methods of
« The regions used in this study are as follows: New England.—Connecticut, Maine, Massachusetts,
New Hampshire, Rhode Island, and Vermont. Middle Atlantic.—New Jersey, New York, and Pennsyl­
vania. Border States.—Delaware, District of Columbia, Kentucky, Maryland, Virginia, and West Vir­
ginia. Southeast.—Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, and Tennessee.
Great Lakes.—Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. Middle West.—Iowa, Kansas,
Missouri, Nebraska, North Dakota, and South Dakota. Southwest—Arkansas, Louisiana, Oklahoma,
and Texas. Mountain.—Arizona, Colorado, Idaho, Montana, New Mexico, Utah, and Wyoming. Pacific.—
California, Nevada, Oregon, and Washington.
The survey covered no production establishments in the Southeast or Mountain regions and no jobbing
shops in the Southwest or Mountain regions.




11
wage payment were important, the average earnings of incentive
workers were higher than those for time workers on the same job;
this tendency was, however, less apparent in the Great Lakes than in
other regions.
On the average, workers in production shops in wage areas contain­
ing cities of 100,000 population or more earned more than did workers
in smaller communities. The differences varied widely; for a few jobs
the differences exceeded 25 percent. In some occupations, on the
other hand, rates were higher in the smaller communities. Variations
on the basis of size of city tended to be greater in the Great Lakes
region than in the country as a whole. They were distinctly more
pronounced among skilled than among semiskilled and unskilled
workers. Some of the unskilled jobs had higher average rates of pay
in the smaller cities than in the large ones; this was particularly notice­
able in New England.
Earnings of tool and die makers in jobbing shops in large wage
areas showed a 15-percent margin over those in small cities; this
difference was representative of the prevailing spread in rates for other
jobs in these shops. A special tabulation based on a group of key
jobs showed an average variation of 17 percent with size of city.
Union production establishments provided pay levels that averaged
about 5 percent above those in nonunion plants, but in about a fourth
of the occupations union wages were, on the average, below those in
nonunion plants. The variation between union and nonunion plants
was greater in the New England and Middle Atlantic regions than in
the Great Lakes region. Among the tool and jobbing establishments,
union shops paid, on the average, about 8 percent more than nonunion
shops. The variation in favor of union plants was found more con­
sistently in the jobbing than in the production shops. In the case of
union tool and die makers the wage difference amounted to 10 percent
for the country as a whole.
In the main, workers paid on an incentive basis in production
shops received more per hour than did time workers on the same job.
(Practically all work in tool and die jobbing shops was on a time basis.)
The average difference in production shops amounted to about 7 per­
cent but was as high as 30 percent in some jobs. In a few categories
higher levels of pay were reported for time workers, primarily as a
result of higher rates of pay for such workers in the Great Lakes
region.
W age and Related Practices

Wartime wage stabilization, because of its limitations on wage-rate
changes, focused attention on so-called “ fringe” issues involving
methods of increasing real income without affecting basic rates of pay.
The procedures by which rates of individual workers were determined
also became a topic of current interest because of the stabilization
program. Data on these practices in the machine-tool accessories
industry were collected in the Bureau’s study.
METHODS OF W AGE DETERMINATION

It was found that most of the establishments in both branches of
the industry paid workers according to a formally established and




12
recognized scale of rates rather than on the basis of individual consid­
erations.
Incentive methods of wage payment were important in the produc­
tion branch of the industry but were used infrequently in tool and
die jobbing shops. In the former, about one-fifth of all plant workers
were paid on an incentive basis; the largest group was employed in
New England, where a third of the workers received incentive pay.
Only 2 percent of all plant workers in jobbing shops were paid in this
manner; most of these were also found in New England, where 10
perpent of the workers were paid piece rates or production bonuses.
HOURS OF W ORK AND SHIFT OPERATIONS

Like other metalworking industries, the machine-tool accessories
industry resorted to lengthened hours of work for individual workers
and to extra shift operations to meet expanded wartime production
needs. These measures, accompanied as they were by premium pay
for extra-shift work and overtime, served to raise gross hourly earnings
of the average worker in the industry well above the straight-time
hourly pay summarized previously.
The range of scheduled workweeks in January 1945 was about the
same in the two branches of the industry, but, on the average, hours
were longer in jobbing shops. About nine-tenths of these latter
plants operated on a scheduled workweek of 48 to 60 hours for men,
the most common hours being 58, 55, and 48 in descending order of
frequency. Two-thirds of the production shops had workweeks of
48 to 55 hours for men on the first shift; the two most common work­
weeks scheduled were 48 and 55 hours. No plants reported a week
as short as 40 hours.
About four-fifths of the production establishments employing
women and over half of the jobbing shops had established a workweek
for women of 48 to 55 hours; only two production shops provided
a 40-hour week.
Production shops operated extra shifts more frequently than did
jobbing shops in January 1945. A fourth of all plant workers in
the former, but only about 15 percent in the latter, were employed
on late shifts. Of the production shops with extra shifts, almost all
provided premium pay for this work.
A second-shift differential was provided in almost three-fourths of
the jobbing shops operating this shift; over half of the plants with a
third shift provided extra pay. The most common types of dif­
ferentials in both branches of the industry were 5 cents for secondshift workers and 10 percent for those on a third shift.
SUPPLEMENTARY W AGE PRACTICES

Information was obtained on provision for paid lunch periods
and bonuses not directly related to production, although their effect
on earnings was excluded from the data presented earlier in this
article. Paid lunch periods were found to be rare. Nonproduction
bonuses (such as Christmas or profit-sharing bonuses) were common
in both branches of the industry, but the amount of such payments
was relatively small in production shops. Data on the extent to which




13
straight-time average hourly earnings were supplemented by these
bonuses were not available for jobbing shops.
These nonincentive bonuses, when averaged over all workers in
the production branch of the industry, amounted to about 1.7 cents
an hour for plant workers and about 1.5 cents an hour for office
workers. In some establishments they exceeded 10 cents an hour.
Such bonuses were more important in the New England States
than in other regions.
OTHER BENEFITS

Formal vacation plans were effective in a large proportion of
the machine-tool accessories establishments studied; insurance plans
were also fairly common. Sick-leave plans, on the other hand, were
reported infrequently.
Vacation plans, though common in both branches of the industry,
were less important in the smaller jobbing shops than in production
establishments. About three-fourths of the latter had formal paidvacation plans for plant workers with a year’s service and about
nine-tenths provided such vacations for office employees with equiv­
alent service. Formal vacation plans for plant workers with a year’s
service were provided by about two-thirds of the jobbing shops; of
the shops that employed an office force, four-fifths provided vacations.
A week’s vacation was the most typical period for plant workers;
half of the plants provided office workers with a comparable vacation.
Two-week vacations were given by half of the production and a third
of the jobbing shops.
Formal provisions for paid sick leave for plant workers with a year’s
service were reported in only 4 of the 156 production shops and 10
of the 623 jobbing shops surveyed, while a fifth of the former group
of establishments and a tenth of the latter had such provisions for
office employees. No information was obtained on informal provi­
sions whereby individual workers who are sick continue to receive
their pay at the discretion of the company.
Over two-fifths of the production and almost a third of the jobbing
shops provided one or more types of insurance or pension plans for
their employees; the proportion was about the same for plant as for
office workers. Life insurance was the most common type of insurance;
health-insurance plans were also frequently reported.
