What would I charge for leaving my family on Easter Sunday?
Well, like many many other people on minimum wage who don't have a choice about working, not a lot!
I don't agree with charging more to do your job just because the timing's a little inconvenient.
Was your life style your choice? Maybe if you were highly qualified you may think differently, my out of hours rates were higher when I was doing proper work. I should add that I am not highly qualified, but have made sure I have some skills that are in demand.
