Remove time off
On Schedule, click the day with the airplane icon.
In Time Off, click Remove Time Off.
The airplane goes away and they can be scheduled.
Don't see Remove Time Off?
Approve and Reject: this is a request. Approve or reject it.
Allow Scheduling: this time off came from your HRIS. Cancel it there. Click Allow Scheduling to schedule them that day anyway.
Good to know: Removing doesn't update your HRIS. It also doesn't give back shifts that became open, so reassign them.
Common questions
