Departments
Most off at once caps how many of a department may be on approved leave on the same working day (0 = no cap). Approving a request that would go over it is refused, naming the day.
Blackout dates
Days when planned leave cannot be booked — a stocktake, a launch, the Christmas rush. For everyone, or one department. Not held to these rules (people are off either way, and they still count toward a cap): Sick leave.
