Adds a new subsection (z) to Section 3 of the Fair Labor Standards Act of 1938 (29 U.S.C. 203) containing new definitions used elsewhere in section 13.

Defines “companionship services” (subsection (z)(1)(A)) as services that provide fellowship, care, and protection for individuals who, because of advanced age or physical or mental infirmity, are unable to care for themselves. It explicitly includes non‑medical in‑home personal care (such as assistance with activities of daily living and instrumental activities of daily living) and household work related to care of the aged or infirm (examples listed: meal preparation, bed making, washing of clothes, errands, assistance to appointments, laundry, medication reminders, bathing, assistance with incontinence and grooming, and other similar services). The definition allows general household work only if it does not exceed 20 percent of the employee’s total weekly hours.

Excludes from “companionship services” (subsection (z)(1)(B)) services that relate to care and protection of the aged or infirm that require and are performed by trained medical personnel, with examples such as a registered or practical nurse.

Defines “domestic service” (subsection (z)(2)) as services of a household nature performed by an employee in or about a private home (permanent or temporary). It lists included employee types and roles (cooks, waiters, butlers, valets, maids, housekeepers, nannies, nurses, janitors, laundresses, caretakers, handymen, gardeners, certified nursing assistants, home care aides, home health aides, personal care aides, chauffeurs of automobiles for family use, and babysitters employed on other than a casual basis).

Defines “third‑party employment” (subsection (z)(3)) as employment of any employee who is engaged in providing companionship services or live‑in domestic services and who is employed by an employer other than the family or household using the services, whether or not the employee provides services to more than one family or household in the same workweek.
