The number of staff you’ll need to cover enough shifts for 24/7 depends on:
The size of your business
The number of roles that need to be on duty at any one time
Your shift length (8-hour shifts, 10-hour shifts or 12-hour shifts)
The amount of wiggle room you want to have for employee time off and sick days
Whether your business has peak hours or periods that require more on-duty staff at certain times of the day
The number of locations your teams are working at
