Working on a bank holiday.

[KukriKhan]

I guess Pape is somewhat right.
It is all negotiation, negotiation, negotiation.
My first IT job didn't pay extra for overtime... well it didn't pay anything as I got a fixed mothly salary.
Big mistake!!

In my next and current job I made sure to put into the contract a clause about overtime.
Basically it states that voluntary overtime only pays the equivalent of an hourly wage and that you can put them into a time bank for later extraction into payment or time off.
Required overtime pays according to state regulation (+50% from 16:00 to 20:00 on weekdays, +50% all hours saturdays up to 20:00, +100% after 20:00 on weekdays and saturdays and +100% on sundays and holydays. An extra hour mealbreak at 17:00 is paid for by the company).
Oh... and we work only 37,5 hours a week, overtime for every hour above this.

That's a pretty complicated formula, but I agree, it's all about negotiation.

Here (US, California, union job) the 'standard' is: Five 8-hour days:

Any hours over 8 per day = +50%,
and any days over 5 per week = +50%.
Night shift = +10% for all hours.
Working any of the 10 federal holidays = +50% all day.

Non-union jobs often pay no overtime at all.
