Yet, Section 138 classifies "any woman who is permitted or suffered to work, with or without compensation, in any night club, cocktail lounge, massage clinic, bar or similar establishments under the effective control or supervision of the employer for a substantial period of time as determined by the Secretary of Labor and Employment" to be an employee "of such establishment for purposes of labor and social legislation."
