The FLSA (29 U.S.C. §§ 206 and 207) requires payment of prescribed wages, including overtime compensation, in either cash or check or similar medium. Overtime compensation must be at time and a half the employees regular rate of pay. The statute allows payment to include the “reasonable cost” or “fair value” of furnishing for an employee with board, lodging or other facilities. 29 C.F.R. § 778.116.
