The interpretations of the law contained in this part are official interpretations of the Department of Labor with respect to the application under described circumstances of the provisions of law which they discuss. These interpretations indicate the construction of the law which the Secretary of Labor and the Administrator believe to be correct and which will guide them in the performance of their duties under the Act unless and until they are otherwise directed by authoritative decisions of the courts or conclude, upon re-examination of an interpretation, that it is incorrect. The interpretations in this part provide statements of general principles applicable to the subjects discussed and illustrations of the application of these principles to situations that frequently arise. They do not and cannot refer specifically to every problem which may be met in the consideration of the exemption discussed. The omission to discuss a particular problem in this part or in interpretations supplementing it should not be taken to indicate the adoption of any position by the Secretary of Labor or the Administrator with respect to such problem or to constitute an administrative interpretation or practice or enforcement policy. Questions on matters not fully covered by this part may be addressed to the Administrator of the Wage and Hour Division, U.S. Department of Labor, Washington, DC 20210 or to any Regional or Area Office of the Division.
