How to lock dates to prevent staff from booking leave
There may be times when all of your staff need to be available and no one should be allowed to book leave.
To block out these dates in Leave Dates, set a leave limit of zero.
Leave limits can be set for individual dates or a range of dates and for specific departments or the entire company.
You can choose set the limit to be a complete block, so that staff can't book any leave at all. Or just show it as a warning to discourage any leave being requested but leaving it to the approver to decide.
