The Priority Group setting allows you to put your Employees into one of ten
groups that can be used if you want to use "AutoFill by priority group."
AutoFill by priority group means that all the Employees in group
1 are assigned to their preferred schedules first (up to their max hours per
week), then once completed, the
group 2 Employees are assigned to the remaining shifts, then group 3, etc
This allows those Employees in the higher rated groups to get more
preferential
schedule assignments, and can help if you have full time employees that you
always want to get their max hours per week.
