The situation is, we have staff who are contracted to work 37.5 hour weeks for a fixed monthly salary. The service is provided 24/7. The staff work a combination of 7.5 and 9.5 hour shifts and an additional payment is made for hours worked over 37.5 hours per week averaged over the month. I need to work out how many additional hours should be paid. Hours are recorded on weekly timesheets and calendar months have odd days e.g. the pay calculation period from 26 September to 25 October has 4 Monday to Sunday weeks and an odd weekend. For full weeks I can compare the hours worked in that week with 37.5 and over the 4 week period come to a 4 weekly total. What should I do with the 2 additional days? Compare hours worked in those days to 37.5/5*2 or 37.5/7*2?
Overtime premium is not an issue, overtime is paid at plain time rates.
