The working hours for full-time employees may deviate by two hours from the standard working week of 38 hours. If you work 40 hours a week, you will be given 96 extra holiday hours per year. See the ‘Flexible working hours’ page for more details.
After consulting with your supervisor, you may have decided that you want to work more hours or less hours. Changing your number of working hours will affect the number of holiday hours that you accrue and it may also affect your salary.
