As used herein, "managerial employees" refer to those whose primary duty consists of the management of the establishment in which they are employed or of a department or subdivision thereof, and to other officers or members of the managerial staff.

"Field personnel" shall refer to non-agricultural employees who regularly perform their duties away from the principal place of business or branch office of the employer and whose actual hours of work in the field cannot be determined with reasonable certainty.

Health personnel in cities and municipalities with a population of at least one million (1,000,000) or in hospitals and clinics with a bed capacity of at least one hundred (100) shall hold regular office hours for eight (8) hours a day, for five (5) days a week, exclusive of time for meals, except where the exigencies of the service require that such personnel work for six (6) days or forty-eight (48) hours, in which case, they shall be entitled to an additional compensation of at least thirty percent (30%) of their regular wage for work on the sixth day. For purposes of this Article, "health personnel" shall include resident physicians, nurses, nutritionists, dietitians, pharmacists, social workers, laboratory technicians, paramedical technicians, psychologists, midwives, attendants and all other hospital or clinic personnel.
