Where an employee performs work during his workweek, some of which
is exempt under one section of the Act, and the remainder of which is
exempt under another section or sections, of the Act, the exemptions may
be combined. The employee's combination exemption is controlled in such
case by that exemption which is narrower in scope. For example, if part
of his work
is exempt from both minimum wage and overtime compensation under one
section of the Act, and the rest is exempt only from the overtime pay
requirements by virtue of section 7(b)(3), the employee is exempt that
week from the overtime pay provisions, but not from the minimum wage
requirements. Similarly, an employee who spends part of his workweek in
work which would, if done throughout the week, exempt him completely
from the overtime pay requirements, and the remainder of the week in
work exempt from such requirements only to the extent and under the
conditions specified in section 7(b)(3), could be exempt from overtime
pay only to such extent and under such conditions. Thus where an
employee spends part of his workweek in transporting petroleum products
by tank truck for an employer in an enterprise described in section
7(b)(3), and the remainder of his workweek in driving a taxicab for the
employer's taxi business (work exempt from the overtime provisions under
section 13(b)(17)), he is eligible for exemption from overtime pay only
if he is compensated in such workweek in accordance with the provisions
of section 7(b)(3) and only to the extent which that section provides.
