There may be employees used by a contractor or subcontractor in
performing a service contract in excess of $2,500 which is subject to
the Act, whose services, although necessary to the performance of the
contract, are not subject to minimum monetary wage or fringe benefit
provisions contained in the contract pursuant to section 2(a) because
such employees are not directly engaged in performing the specified
contract services. An example might be a laundry contractor's billing
clerk performing billing work with respect to the items laundered. In
all such situations, the employees who are necessary to the performance
of the contract but not directly engaged in the performance of the
specified contract services, are nevertheless subject to the minimum
wage provision of section 2(b) (see Sec. 4.150) requiring payment of not
less than the minimum wage specified under section 6(a)(1) of the Fair
Labor Standards Act to all employees working on a covered contract,
unless specifically exempt. However, in situations where minimum
monetary wages and fringe benefits for a particular class or classes of
service employees actually performing the services called for by the
contract have not been specified in the contract because the wage and
fringe benefit determination applicable to the contract has been made
only for other classes of service employees who will perform the
contract work, the employer will be required to pay the monetary wages
and fringe benefits which may be specified for such classes of employees
pursuant to the conformance procedures provided in Sec. 4.6(b).
