In order to meet the requirement of actual employment ``by'' the
establishment, an employee, whether performing his duties inside or
outside the establishment, must be employed by his employer in the work
of the exempt establishment itself in activities within the scope of its
exempt business. (See Davis v. Goodman Lumber Co., 133 F. 2d 52 (CA-4)
(holding section 13(a)(2) exemption inapplicable to employees working in
manufacturing phase of employer's retail establishment); Wessling v.
Carroll Gas Co., 266 F. Supp. 795 (N.D. Iowa); Oliveira v. Basteiro, 18
WH Cases 668 (S.D. Texas). See also, Northwest Airlines v. Jackson, 185
F. 2d 74 (CA-8); Walling v. Connecticut Co., 154 F. 2d 522 (CA-2)
