Extra Shifts vs Offered Shifts vs Unassigned Shifts

Shifts normally have staff members assigned. Some special shifts do not have a staff member listed.

Extra Shifts

Extra shifts are available for any staff member to take as long as they have the same skill/role assigned as the shift. Other limitations and restrictions can apply including venues, hour limits, enforced rest and more. 
You can now choose to limit particular extra shifts to a limited selection of staff within the shift’s skill. This allows you to send the shift as an extra (first come, first served) but to only specific people.
 

Unassigned Shifts

These shifts are not available for staff to take themselves and must be manually assigned to the staff member. This is done in the same way as transferring a shift between staff members via Shift Week, Shifts Grid or Shift Timeline.

Offered Shifts

These shifts are between Extra and Unassigned shifts. Staff will receive a notification about this type of shift, however they can only offer to work the shift, they won't automatically receive the shift. Once offered, a manager can then select the staff member to assign to the shift. Normally this is from those who have offered to work, however you can also choose any staff member if none are suitable. Managers are also able to see the date and time that a staff member submitted the offer to work.
