WorkRoster has a unique Availability system that includes:
Employees can quickly and easily indicate their future availability on the roster with the click of a button. They can mark themselves as available (free) or unavailable (busy) on an hourly, daily or weekly basis.
Managers can clearly see each employee's availability on the shift assignment menu
Availability is also clearly shown next to shift assignments.
The Availability feature is optional and can be completely disabled in Workforce Settings if it's not needed.
Managers find using the Shift Agreements feature handy to check on employee acceptance or acknowledgement of assigned shifts.
