On-call scheduling, sometimes referred to as on-call shifts, are processes used in business where employee work schedules are intentionally unpredictable. Employees who work on-call are expected to be available at any time during their shift, usually with short notice, to carry out their working duties. Depending on the nature of the profession, on-call duties may vary from what is expected during normal working hours to emergency cover only.
