Must I work full-time to be exempt?
No. Part-time employees can be exempt as long as they are permanent or probationary employees who do not otherwise practice law. The words "those employed full-time ... who do not otherwise practice law" in sections 2.54(A)(3) and 2.54(A)(4) refer to employees "employed on a permanent or probationary basis, regardless of their working hours, who do not practice law in California" except as employees of the State of California or the United States government.
