Groomer scheduling will help you schedule appointments when your employees are scheduled to work.
Groomer select boxes will only show you groomers working on the date of the appointment you are creating or updating. If an appointment starts outside of the selected groomer's schedule you will see a warning. The groomer select boxes will also show you the hours each person is scheduled on that date.
Start with creating a default schedule for all of your Groomers. The default schedule will repeat weekly forever.
If a schedule change is necessary, go to the current schedule and edit the default shift for that employee.
