DECISION ON REVIEW AND DIRECTION OF
ELECTION
By CHAIRMAN MILLER AND MEMBERS FANNING AND
PENELLO
On October 19, 1973, the Regional Director for
Region 4 issued a Decision and Direction of Election
in the above-entitled proceeding in which he found,
in accordance with Petitioner's request, that a unit
confined to draftsmen in the engineering division of
Employer's Allentown, Pennsylvania, facility was an
appropriate unit. In so finding, the Regional Director
rejected the Employer's contention that all of the
Employer's engineering division employees located
in three separate cities should be included in the unit
or, in the alternative, that all engineering division
employees located at Allentown constitute the small-
est appropriate unit.
Thereafter, in accordance with Section 102.67 of
the National Labor Relations Board's Rules and Re-
gulations, Series 8, as amended, the Employer filed a
timely Request for Review with the National Labor
Relations Board in which it claimed that the Region-
al Director erred in rejecting its unit contentions. It
further claimed that in no event could a unit com-
posed solely of draftsmen be found to be appropriate
under the Board's established unit rules allegedly be-
cause: (1) the draftsmen enrolled in the engineering
division at Allentown composed only a segment of a
much larger class of employees within the engineer-
ing division who shared a substantial community of
interest with one another; and (2) draftsmen were
only one of many other classifications of unrepre-
sented technical employees employed by the Em-
ployer both within and outside the engineering divi-
sion.
On December 19, 1973, the Board denied the
Employer's Request for Review with respect to the
Regional Director's finding that a unit consisting
solely of draftsmen was appropriate. However, the
Board remanded the matter to the Regional Director
to direct a further hearing to obtain evidence as to
whether there were "other unrepresented technical
employees employed within the Engineering Division
or elsewhere in the Employer's Allentown facility."
A hearing was held January 29 and 30 and Febru-
ary 21, 1974, before Hearing Officer Dorothy L.
Moore. All parties were represented by counsel and
were afforded full opportunity to be heard, to exam-
ine and cross-examine witnesses, and to introduce
evidence bearing on the issues raised. The parties'
stated positions at that hearing evidenced uncertain-
ty as to what unit issues were open for review. There-
fore, on May 20, 1974, the Board issued a Notice To
Show Cause which (1) clarified the remand order
with respect to the unit issue, and (2) directed that
the parties show cause why a unit composed of all
nonsupervisory, nonprofessional employees in the
engineering division of the Allentown, Pennsylvania,
facility excluding only employees classified as file
clerks,
typists,
microfilm clerks, and secretaries
would not be an appropriate unit under established
Board unit precedents.
Thereafter, both Petitioner and Employer filed an-
swering briefs to the Notice To Show Cause.
Pursuant to the provisions of Section 3(b) of the
National Labor Relations Act, as amended, the Na-
tional Labor Relations Board has delegated its au-
thority in this proceeding to a three-member panel.
The Board has considered the entire record in this
case with respect to the issues under review, includ-
ing the briefs on review, and hereby affirms the Re-
gional Director's decision only to the extent consis-
tent herewith.
1. THE APPROPRIATE UNIT
A. The Parties' Contentions
The Petitioner initially requested a unit confined
to "draftsmen" in the Employer's engineering divi-
sion located in Allentown, Pennsylvania. In the
briefs filed subsequent to our order granting review
and our Notice To Show Cause, Petitioner indicated
its willingness to accept, as alternatives, units broad-
er in scope than that initially requested, though con-
fined, nonetheless, to employees who are employed
in the Allentown engineering division. Thus, alterna-
tively it proposed either a unit composed of employ-
ees who could be identified as "technicals" within the
meaning of the Board's normal definition of that
term, or a unit of substantially all nonsupervisory,
nonprofessional employees, but excluding that part
of the complement classified as laboratory drivers
and mechanics employed, mainly, at the Employer's
"Test Shed." Petitioner objected to the inclusion of
"Test Shed" employees because it claimed that they
were production and maintenance employees and,
therefore, should be excluded from the unit found
appropriate.
The Employer's position, as ultimately developed
at the hearing held in January and February 1974,
214 NLRB No. 57
MACK TRUCKS, INC
and in the briefs filed thereafter, does not dispute the
appropriateness of a unit composed of all, or sub-
stantially all, of the nonprofessional, nonsupervisory
employees employed in the engineering division at
the Allentown facilities. The Employer, however,
would exclude from such unit all employees classi-
fied as file clerks, typists, microfilm clerks, and secre-
taries.
It asserts that all employees classified as
draftsmen, machine operators, record clerks, sched-
ule clerk, change writers, engineering aides, staff as-
sistant, assistant engineers, laboratory drivers, and
laboratory mechanics share job interests so closely
related as to preclude their fragmentation. For rea-
sons hereafter set forth, we find merit in this latter
stated position of the Employer.
There is no bargaining history among any of the
employees of the Employer's engineering division
and no labor organization currently represents any
such employees.'
B. The Facts
The Employer is a corporation engaged in the
manufacture and sale of trucks. It designs, fabricates,
and assembles all of the component parts of the
trucks it manufactures and sells. Although it has fa-
cilities located in other parts of the United States, it
conducts the major portion of its operations at the
facilities located at Allentown, Pennsylvania-the
sole location with which we are here concerned.' It
has allocated to the engineering division-which is
composed of several departments-all responsibili-
ties related to product development, product engi-
neering, and design function. It operates that division
as an integrated corporate function, as distinguished
from its operation of other departments which per-
form plant functions.
The engineering division is headed by the execu-
tive vice president of products and engineering (Mr.
W. M. May) who is located at the World Headquar-
ters Building in Allentown, Pennsylvania. The divi-
sion is organized into two major subdivisions, prod-
uct engineering and product development, each
headed by a vice president, also located at the World
Headquarters Building. Each such subdivision has
four departments, each of which is headed by a chief
engineer. Four of these eight departments, plus engi-
neering administration, are located at the Allentown

rately, production and maintenance employees and office clerical employ-
ees in other divisions of the Allentown, Pennsylvania, facilities

ognition of any engineering division employees

Maryland, and Hayward, California Its corporate headquarters are located

facilities . Two departments, namely, highway vehicle
engineering and special purposes vehicles, are locat-
ed, mainly, at the World Headquarters Building. The
vehicle development department is situated both at
the World Headquarters Building and a few miles
away at the Union Boulevard facility. The vehicle
development laboratory department is located at the
"Test Shed," approximately 1-1/2 miles from the
World Headquarters Building. The record reveals,
however, that a new building is under construction
about a mile from the World Headquarters Building,
to be occupied in winter of 1974 by both the vehicle
development department and the vehicle devel-
opment laboratory department. After this construc-
tion is completed, all four departments of the engi-
neering division at Allentown will be centralized at
two locations; i.e., the World Headquarters Building
and the new facility.
The different job classifications of employees in
the engineering division are spread throughout the
four departments and the functions of the four de-
partments are interrelated.' Draftsmen and engineers
work in all four departments.
The engineering division, as a whole, is maintained
primarily for the purpose of research, design, and de-
velopment of new products, and for the specialized
design of custom orders. Its day-to-day work activi-
ties are, in the main, determined by professional em-
ployees, most of whom are professional engineers.
Apart from supervisors, the other employees in the
division, approximately 265 in number, perform sup-
porting job functions under the general direction of
the professionals. Of these 265 employees, about 25
occupy classifications which all parties would de-
scribe as "office clerical" within the meaning of the
Board's definition of that phrase, viz, file clerks, mi-
crofilm clerks, typists, and secretaries. The remaining
240 occupy various classifications as follows: about
156 are engaged as draftsmen,' 13 as machine opera-
tors, 11 as records clerks, I as schedule clerk, 15 as
change writers, 7 as engineering aides, 4 as laborato-
ry drivers, 30 as laboratory mechanics, and 3 as assis-
tant engineers.5
We find that the following classifications belong in
the unit we find herein to be appropriate for the pur-

classifications of the engineering division employees are related only to the
employees who worked at the facilities located at or near Allentown, Penn-
sylvania , hereafter identified as the "Allentown-based " employees
Each broad job classification has a number of subclassifications and
grades
5 Although some of these employees were listed on a "clerical" payroll
list, the Employer argued that all of them were technicals Petitioner con-
tended that only the draftsmen and the assistant engineers were techmcals,
and the others were office clerical or production and maintenance employ-
ees Considering the view we are taking of this case , we find it unnecessary
to determine the dispute regarding the technical status of some of these
employees

poses of collective bargaining. The record shows the
following with respect to the interrelationship of
these employees and their duties:
Draftsmen: The employees occupying the drafts-
man classifications perform the type of work normal-
ly associated with that title. They work in the various
departments in squads under the immediate supervi-
sion of the drafting "squad leaders," admitted profes-
sionals. They either majored in drafting in high
school or took specialized drafting courses after they
finished high school. Of those employees currently
occupying the position of draftsman, 75 began their
employment in job classifications below described.
Draftsmen work closely with the professional engi-
neers who review their work. The blueprints they
produce are turned over for reproduction to the em-
ployees occupying the machine operator classifica-
tions.
Machine Operators: The employees classified as
machine operators are subdivided into three job-title
groups: machine operator leader, machine operator
A, and machine operator B. Their common primary
work task is to operate and maintain the Employer's
various reproduction machines. They work in engi-
neering administration and are supervised by the re-
production supervisor, H. H. Heistrand, who also
supervises four record clerks. Heinstrand reports to
L. U. David, engineering administration manager.
All of them have frequent day-to-day contact with
draftsmen whose work they reproduce and a number
of them have had some training in drafting work as
such. Indeed, it is the established practice of the Em-
ployer to employ as machine operators B applicants
with some drafting training, and to promote them to
draftsman classifications when they complete their
drafting courses. Six of the machine operators-
those occupying the machine operator B classifica-
tions-are currently studying to become draftsmen.
Change writers: There are three classifications of
change writers: change writer leader, change writer
A, and change writer B. They work in engineering
administration and are directed by A. A. Zellner, the
change writer supervisor, who also reports to L. U.
David, engineering administration
manager.
The
change writers all have a high school education and
many took drafting courses in high school. The
change writers compile manufacturing lists (ML);
i.e., lists of parts and assemblies needed to complete
and maintain a Mack truck. When the change writers
have a "change" to write they receive a "header
sheet" from the drafting department. This sheet out-
lines what the drafting department is doing, why it is
being done, and what references the draftsmen have
as far as described differences between old and new
parts. Along with the "change," change writers also
receive blueprints from the draftsmen. From these
blueprints, the change writers set up new manufac-
turing lists which incorporate these changes and
itemize all parts of a model. If a change writer has
any questions regarding blueprint, he confers with a
draftsman. After the ML is prepared, the change
writers make up a set of "requirement cards" 6 and
then write up an "engineering change notice." The
latter is composed from information obtained from
the drafting department. Before the change can be
issued, the change writer must get the approval of a
drafting squad leader or group supervisor.
As is obvious from the foregoing, the tasks per-
formed by change writers require constant contact
with draftsmen.
Records clerks: This classification is divided into
records clerk A and records clerk B. Four records
clerks are supervised by H. H. Heistrand, the re-
production supervisor; two are supervised by the en-
gineering administration manager; and the rest are
supervised by the various heads of the subdepart-
ments in highway vehicle engineering. All records
clerks have high school diplomas and their work re-
quires the ability to read blueprints. Two of those
currently employed as records clerks B have taken
courses in drafting with the intent of becoming
draftsmen.
The records clerks all perform different duties.
Four of them are primarily engaged in maintaining
histories of all changes as reported to them by the
draftsmen, from the drafting stage to production.
Each has a specific area or responsibility: one works
with vendor prints; another with fire or special re-
leases; another with standard drafting changes; and
the last keeps records of the drafting done for cus-
tomer orders. Each of these records clerks receives
the change information from the draftsmen, and
must clear with the draftsmen any questions or prob-
lems he might have regarding a change.
Of the two other records clerks, one has the re-
sponsibility of gathering information, as released by
the standard production design area, to determine
what compliance is necessary to meet safety regula-
tions. Practically 100 percent of his time is spent con-
ferring with drafting squad leaders and draftsmen.
Another records clerk has the responsibility of keep-
ing draftsmen current as to production requirements
to insure that the drafting department is keeping up
with the general sales orders. His work also requires
constant contact with draftsmen.
Schedule clerk: The single schedule clerk works in
the highway vehicle engineering department under
6 Each Mack part has a requirement card which indicates the part num-
be r, the title, the color, the code, and on what model truck it appears
MACK TRUCKS, INC
the supervision of the supervisor of customer order
drafting. He works in a room with 50 to 60 draftsmen
and is in contact with drafting squad leaders on a
daily basis. His primary function is to receive general
sales orders and distribute them, according to their
model number, to one of the four drafting squad
leaders. The schedule clerk also maintains a daily
"promise and place schedule" which serves as a
guide to drafting squad leaders for the assignment of
drafting tasks.
Engineering aides: Each of the seven employees
classified as an engineering aide has a different
function. They work throughout the various depart-
ments of the engineering division and are supervised
by the supervisors of the subdepartments in which
they work. One engineering aide processes the pat-
ents developed by the employees in the engineering
division; another handles deviations that have to be
made in manufacturing lists due to changes in speci-
fications by reason of the requirements of foreign
countries or because of shortages due to the failure of
the vendor to deliver; another orders special equip-
ment for new orders of fire apparatus; another stud-
ies
the engineering experimental releases to de-
termine what new material needs to be ordered; an-
other orders parts necessary for "running prototype
models"; another procures the weights of all Mack
units, records them, and works up weight estimates
for the sales department; another does liaison work
between the portion of the engineering division in
Hagerstown and that in Allentown; and yet another
does liaison work at the test shed which involves in-
suring that the test shed employees have all the mate-
rials necessary to conduct tests. Although not all of
the engineering aides have daily contact with the
draftsmen, the undisputed evidence shows that the
engineering aide who does liaison work between
Hagerstown and Allentown and the one who does
liaison work at the test shed are in daily contact with
draftsmen. Two of the employees who are currently
engineering aides formerly occupied the classifica-
tion of draftsmen.
The engineering staff assistant works in the division
headquarters under the supervision of L. L. David,
engineering administration manager. He estimates
the cost of the engineering work required for various
projects. Using a rough estimate of what a project
will cost, he determines the areas of engineering
which are involved and how the available funds
should be allocated. A substantial amount of the in-
formation which he needs he obtains from the em-
ployees listed above.
Assistant engineers: ' They work under the direc-
7 Petitioner's willingness to include the assistant engineers in its primary
385
tion of the chief engineer in the vehicle development
laboratory. They work with the laboratory mechanics
and engineers in the test shed and, on occasion, they
test-drive the prototype trucks along with the labora-
tory drivers. Each of the three employees currently
classified as assistant engineers formerly worked for
the Employer as draftsmen.
As noted, the parties disagree with regard to the
inclusion of laboratory drivers and mechanics in the
unit. Petitioner contends that these employees are
production and maintenance employees and should
therefore be excluded from the unit. We disagree. We
find, for the reasons explained below, that there is a
sufficient community of interest among these em-
ployees and the other engineering division employees
to warrant their inclusion in a divisionwide unit.
Laboratory drivers come under the supervision of
the chief engineer of the vehicle development labora-
tory. They test all components of a newly designed
truck in prototype-"engines, brakes, tires,-any-
thing that is in the Engineering Division." They per-
form their work under the guidance of engineers
(professionals) who explain to the drivers what to ex-
pect during a test drive and what to do should a
failure occur. Occasionally, the engineers will accom-
pany the drivers on test runs. Performance of their
assigned task also involves some contact with the
draftsmen, particularly when a new part is being put
on a prototype truck. At such times, draftsmen show
the driver how to install the new part and explain
what to expect during testing of that part. The labo-
ratory drivers work out of the test shed, about 1-1/2
miles from the World Headquarters Building.
Laboratory mechanics: This classification is divided
into four groups, largely the basis of experience and
skill:
laboratory mechanic leader, laboratory me-
chanic A, laboratory mechanic B, and laboratory
mechanic helper. They are supervised by engineers.
The majority of these employees work in the vehicle
development and testing laboratory (test shed). This
is the same test shed where the laboratory drivers
work. The remainder of the employees in this classifi-
cation work in the vehicle development department
at another location-the Union Boulevard facility-
which is about 3 miles from the World Headquarters
Building. However, as stated above, both the vehicle
development department and the vehicle devel-
opment laboratory will be combined into one facility
by winter 1974.
The laboratory mechanics, working under the di-
rection of a test engineer, for the most part perform
physical tests of prototype vehicles and their compo-
nent parts. The tests are conducted as chassis, bench,

steering, and driving tests to determine stress, cooling
ability, performance, fatigue, strength, and durability
of the vehicle and its parts. Other tasks involved the
assembly, disassembly, and replacement of compo-
nent parts being tested and developed. As part of
their job qualifications, the laboratory mechanics
must be able to read and interpret blueprints, as well
as written engineering instructions and orders.
The laboratory mechanics have daily contact with
draftsmen, as well as with test engineers under whose
guidance they work. When the design of a new part
of a prototype truck must be changed, a draftsman
will come to the test shed and work with the engineer
and laboratory mechanic in the modification of the
design of the new part. Draftsmen are also required
to come to the test shed to record any changes that
the mechanics or engineers may make in the design
of a new part or a prototype truck.
II. DISCUSSION AND CONCLUSION
The records shows that all of the engineering divi-
sion employees are salaried and enjoy the same
fringe benefits (holidays, sick benefits, vacations, life
and accident insurance, stock purchase plans, medi-
cal and hospital insurance, and cafeteria and parking
facilities). The salary grade structures of the drafts-
men, machine operators, records clerks, schedule
clerk, change writers, engineering aides, engineering
staff assistant, assistant engineers, laboratory drivers,
and laboratory mechanics cut across all job classifi-
cations. In fact, many of the employees, listed as
"clerical" and "laboratory" employees on the pay-
roll, earn greater salaries than the draftsmen. The
employees have the same hours of work, wear similar
badges, and are paid out of the same centralized en-
gineering division payroll. As indicated above, there
are frequent transfers from one classification to an-
other within the division. Except for the laboratory
drivers, mechanics, clerks, and engineers who work
at the test shed, and the employees who work at the
Union Boulevard facility, the employees all work at
one central location-the
World
Headquarters
Building-where they share common or overlapping
supervision. As stated, a new facility is currently
being built which, when opened, will house both the
test shed employees and the Union Boulevard em-
ployees at one location. At that time all draftsmen,
clerks, laboratory mechanics, and drivers will share
either one or two common buildings, as well as com-
mon supervision.
The foregoing facts establish the validity of the
Employer's position that no less than a grouping of
engineering division employees engaged as drafts-
clerk, change writers, engineering aides, engineering
staff assistant, assistant engineers, laboratory drivers,
and laboratory mechanics may properly be estab-
lished as "an" appropriate unit.
It cannot be gainsaid that all of these employees,
including those working at the test shed, compose a
functionally integrated group whose tasks are com-
monly directed toward research and development
and are performed, largely, in one location and in
one administratively indentifiable section of the
Employer's operation. While the above-described
employees perform dissimilar tasks, the work of the
employees in each classification relates to one com-
mon project, determined and planned by the profes-
sional employees of the engineering division.
Contrary to the contention of the Petitioner, the
fact that not all of the engineering division employ-
ees above described may be properly identified as
"technicals," within the Board's definition of that
term, affords no basis for treating such employees
separately from others for unit purposes. The Board
has not, since its decision in The Sheffield Corpora-
tion, 134 NLRB 1101 (1961), held that technical em-
ployees must be represented apart from others where,
as here, the evidence discloses that the claimed tech-
nicals are but one segment of a functionally integrat-
ed group of employees performing interrelated tasks.'
Nor do we find any merit in Petitioner's attempt to
justify its primary unit proposal on the ground that
all the engineering division employees, other than
those identified as technicals, are "office clericals." It
is true that most of these employees work in an of-
fice, as distinguished from a plant location, but it
does not follow that all must be labeled as "office
clerical" employees. Indeed, it seems to us that to
attach the label of "office clerical" to employees clas-
sified as machine operators, records clerks, schedule
clerk, change writers, engineering staff assistant, and
engineering aides would be to disregard the fact that
the functions they perform within the division are
clearly functions in support of tasks performed by
those whom Petitioner identifies as "technicals" and
are interrelated. It seems to us that these functions
are, in a real sense, analogous to those performed by
plant clerical employees supporting a production
operation's work and, like plant clericals, they func-
tion as an integral part of that division's operation.
We also find that a similar determination is justi-
fied with respect to the functions performed by labo-
ratory drivers and mechanics for the admitted tech-
nical and professional employees within the engi-
neering division. We find no merit in Petitioner's

contention that these are production and mainte-
nance employees and, as such, should not be includ-
ed within a unit of engineering division employees
but should be represented in a production and main-
tenance unit. We find that these employees are func-
tionally integrated with the rest of the engineering
division, as their duties at the test shed form an integ-
ral part of the engineering operations and processes
within the engineering division.
All parties agree, and we find, that file clerks, mi-
crofilm clerks, typists, and secretaries are clearly
identifiable as "office clerical" and hence must be
excluded from the unit.
Accordingly, we find, subject to the condition indi-
cated below,' that the following constitute an appro-
priate unit:
