Shifts Swap portions of your shift.
Ability to have someone cover your shift entirely or just a portion. Example I need to take off 2 hours early but I only need to offer up those 2 hours to someone else. I will work the rest of the 8 hour shift.
This should be done also for requests, I can ask 2 free hours and it should be possible to update the shift accordingly after the manager approves the request.
