I work for a chain that has both equity and franchise stores. Before going on mat leave I worked for an equity store as a supervisor but we've moved and I found an opening at a franchise store. The franchise sets their own payscale so it pays about £1 less per hour at £7.70 for a supervisor. Not great but they were willing to accommodate my specific shifts and I've not been able to find a better offer as yet. Went in to sign the contract yesterday and they asked how old I am. Because I'm 24 I will be actually be getting £7.20 per hour. I'm a bit gutted, firstly that I'll be getting less than I thought but also that the difference between minimum wage and supervisor wage is not the same as for over 25s. £6.95 is min for 21-24 so I'll get an extra 25p for being a supervisor but if I was 25 I'd be getting 50p extra for being a supervisor. I still signed, I really need to get back to work if only for my own sanity and beggars can't be choosers but AIBU to think that I should be paid the same for doing the same work as someone a year older than me or at the very least be getting the same amount extra for being a supervisor?
