Section 13(a)(6)(E) which was added to the Act by the Fair Labor
Standards Amendments of 1966 provides an exemption from the minimum wage
and overtime requirements of the Act for any employee ``employed in
agriculture'' if he is ``principally engaged in the range production of
livestock.'' It is apparent from the language of section 13(a)(6)(E)
that the application of this exemption depends on the type of work
performed by the individual employee for whom exemption is sought and on
where the work is done. A determination of whether an employee is exempt
therefore requires an examination of that employee's duties and where
they are performed. Some employees of the employer may be exempt while
others may not.
