If you have active and open (with no assigned employee) shifts, you can let your staff members pick up those shifts.

Such shifts are marked as Open Shifts and are visible in the Full Schedule page accessible by your staff members.

Open shifts

Pick up a shift

After an employee has picked up a shift, they get assigned to the shift, and the shift becomes Draft so the admin can approve the pickup. You can also configure it in the settings if the shift automatically becomes Active so no admin interaction is required.
