29 CFR 784.4 - Significance of official interpretations.
The regulations in this part contain the official interpretations of the Department of Labor pertaining to the exemptions provided in sections 13(a)(5) and 13(b)(4) of the Fair Labor Standards Act of 1938, as amended. It is intended that the positions stated will serve as “a practical guide to employers and employees as to how the office representing the public interest in its enforcement will seek to apply it” (Skidmore v. Swift, 323 U.S. 134, 138). 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 contained herein may be relied upon in accordance with section 10 of the Portal-to-Portal Act ( 29 U.S.C. 251- 262 251-262), so long as they remain effective and are not modified, amended, rescinded, or determined by judicial authority to be incorrect.
