The exemptions under Section 13(a)(1) of the Fair Labor Standards Act never reach manual laborers or other “blue collar” workers who do repetitive work with their hands, physical skill, and energy — no matter how highly paid they are. The regulation is explicit that employees like carpenters, electricians, mechanics, plumbers, iron workers, operating engineers, longshoremen, and construction laborers gain the skills their work demands through apprenticeship and on-the-job training, not through the prolonged course of specialized intellectual instruction that a learned-professional exemption requires. A relief or working supervisor is a different case. If that supervisor’s primary duty is nonexempt production work performed alongside the crew, then occasionally directing other workers while the regular exempt supervisor is unavailable does not by itself create an exemption. Primary duty is still judged on the facts as a whole, including how the employee’s pay compares with the nonexempt workers doing the same kind of work.

The same flat exclusion covers police officers, detectives, deputy sheriffs, state troopers, correctional officers, firefighters, paramedics, EMTs, and similar first responders, “regardless of rank or pay level.” Their work — fighting fires, apprehending suspects, investigating crimes, interviewing witnesses — is not management of an enterprise, not office work tied to the employer’s business operations, and not the specialized intellectual field of a learned profession, so none of the three white-collar exemptions (executive, administrative, or professional) can reach it. The regulation adds a pointed example: a police officer or firefighter who also directs other employees during an investigation or a fire is still not an exempt executive, because directing that one task is not the same as managing a department.

What actually distinguishes an exempt role from these excluded ones is the primary duty test itself, as covered earlier in this chapter. An exempt executive’s primary duty is managing the enterprise or a recognized department, customarily and regularly directing the work of two or more employees, with real hiring-and-firing authority or influence over it. An exempt administrative employee’s primary duty is office or non-manual work tied to the employer’s — or the employer’s customers’ — management or general business operations, exercising discretion and independent judgment on matters of significance, such as authority to commit the employer on matters with significant financial impact, or to formulate or implement management policies. A title like “supervisor” or “manager” proves nothing on its own; the question is always what the employee’s primary duty actually is.
