Big supermarkets in the UK are open 24 hours a day for most days of the week, shutting early on Sundays for some reason. I don't think we got paid a lot more than the day staff, if anything. I guess if you get rid of penalty rates your stores would be able to open 24 hours as well. At least we won't have 15% surcharges. I really used to enjoy the penalty rates when I was working in that field, needed the money so giving up a weekend and getting extra money in the bank was always a bonus, really helped out when I was younger and just getting on my feet. Haven't had a job that needed me in at the weekends for a long time now, don't miss them.
