The pattern of days you work can affect whether you work more or fewer days than your contractual entitlement.
For example:
Staff who work Mondays may work additional days because some public holidays fall on Mondays.
Staff who do not work Mondays may sometimes work fewer days overall.
It is important to compare:
The number of days you are expected to attend basedon your timetable, and
The number of days covered by your salary allocation.
