Interesting question.  For me personally, it's something I've always wanted to do and I'm still stubborn and naieve enough to do it.  One day, once the kids are older.  The shift work is what it is, and working with people you're always going to be in the wrong irrespective if you're a bus driver or shop worker.  Ultimately though it all boils down to money.  It would be a pay cut for me. Assuming the top end of the scale is £11.50-£12.00 ph I could just about get passed my wife.  But not the minimum wage training and £9.00 ish starting rate.
