What percentage can all the nights, weekends etc equate to of the annual salary? 10% 20%?
I feel there is so much room for interpretation, grade 7 on 12 hour shifts? Come the end of the year all that unsociable hours must add up on top of the annual salary?
Depends how many rest days you are prepared to work. I'm a grade 8 and last tax year nights, Sundays and an average of 2 rest days per pay period put approximately 40% on top of Headline pay.
