This is a question on usual hours.
We pay monthly, (fixed amount) and work fixed hours per week.(37).
However, the 'usual hours' in each month will obviously vary according to weekdays.
For July, if I look at Mondays to Fridays, I get 170 hours in total. (we work 7.5 Mon to Thur and 7.0 on Friday
Taken over a year, we should be working 52 weeks x 37 hours = 1924, which would be 160.33 per month. (We ignore the odd day in the year)
Are my usual hours 170, or 160.33?
I guess August might move the other way.
Our contracts are not specified in hours per month or hours per year.
On the plus point - I quite like the calculation the .gov site spits out - I can understand it. With the caveat that I put start and end dates as 1st and last day of the month, and don't get involved in the fact our pay day is 28th.
