The average hours per week are calculated by taking the total number of scheduled hours across all weeks in the rota and dividing that by the number of weeks.
Example
If an employee is scheduled to work 37.5 hours for 5 weeks and 22.5 hours for another 5 weeks, the calculation would be:
5 weeks × 37.5 hours = 187.5 hours
5 weeks × 22.5 hours = 112.5 hours
Total hours = 187.5 + 112.5 = 300 hours
Total weeks = 10
Average hours per week = 300 ÷ 10 = 30.0 hours
This gives an average of 30.0 hours per week.
