After a night's sleep, I have been reading the Cumbrian document again. It is still complicated, but from it I think I see that (in this county anyway) -
Currently they all had 39 weeks working and 13 weeks holiday.
Hourly rate
The current hourly rate is based on working 32.5 hours as their full time hours.
so if they earn
£16830 / 1694.6428525 (32.5hrs x 52.142857weeks) = £9.93123 per hour
In the future the standard full time hours would be 37 hours (Are there children in school to be assisted for those 37 hours? If not, how will they work without them? If so, then they must have been working more than 32.5 hours already?)
If they earn £ 16830 / 1929.2857 (37 x 52.142857) = £8.7234 (not £9.93123 as it was when the full weekly hours were set at 32.5)
Therefore their hourly rate will reduce, but their nominal hours will increase to make their monthly pay the same.
In future people with a full year contract will have 39 weeks working plus 7.6 weeks (38 days) paid holiday - 45.65 weeks. (previously 13 weeks holiday - a difference of 5.4 weeks, not 8)
To work out their pay,
Weekly Hours x hourly rate x 45.6 weeks = annual salary
Which lowers their pay - but it is only one net reduction, not the two separate ones that *dj thought* (no, jen, I am not saying this is a good thing, just that it could be a bit less bad than it first appeared to you)
This is then divided by 12 months so they get the same amount each month.
People with a term-only contract have 39 weeks working and pro-rata holidays depending on how many hours a week they work.
So - someone with 4 years service, working 20 hours a week -
Annual Salary = £16830
Working 20 hours per week
39 weeks working
4 years service
Hourly rate
£16830 / 1929.2857 = £8.7234
Annual Salary
Hourly rate x hours per week x weeks worked plus hols
£8.7234 x 20 X 45.4502 = £7929.63
Gross monthly salary
£7929.63 / 12 (months in the year) = £660.80
