While there is no precise definition of what shiftwork is, most studies on shiftwork classify shiftworkers as anyone working outside regular daytime hours (i.e. between approximately 7 AM and 6 PM, Monday through Friday). Under these definitions, shiftworkers include all people working evening shift, night shift, rotating shifts, split shifts, or irregular or on-call schedules both during the week and on weekends.
