When a block of shifts is no longer needed — say an outbreak clears — you can cancel them together instead of one at a time.
Open Shifts.
Select the shifts you want to cancel, or use the bulk-cancel option.
Choose to cancel the selection and give a reason.
Confirm. Any booked workers on those shifts are notified automatically.
Cancel as early as you can — late cancellations leave workers who had planned their week around a shift. To cancel a single shift, see the article on cancelling a shift. If you only need the time changed, don't cancel — see the article on changing the time of a shift.
