An employee whose agricultural employment meets the tests for
exemption may engage in ``other'' employment ``in connection with'' his
employer's livestock auction operations under the conditions stated in
section 13(b)(13). The work which an employee may engage in under the
phrase ``in connection with'' includes only those activities which are a
necessary incident to conducting a livestock auction of the limited type
permitted under the exemption. Such work as transporting the livestock
and caring for it, custodial, maintenance, and clerical duties are
included. Work which cannot be considered necessarily incident to the
livestock auction is not exempt.
