Bank holidays on their own are generally meaningless these days though, what really matters is holiday allowance so unless that's part of the policy too then it's probably not a big difference. I'm starting a new job with 28 days + 8 public holidays and if we lived in a 12 holidays country instead of an 8 holidays country I doubt I'd be being offered as much as 28 days on top of that 12. Maybe it wouldn't be a whole 4 less so some people may see a benefit, but I think it'll still be less.
My wife works in retail and I think she gets the the legal minimum which is 28 days which works out as 20 days + 8 public holidays but she has to work most bank holidays anyway so unless the minimum rises from 28 I think she'll end up with 16 days + 12 public holidays that she'll probably have to work anyway.
Anyway I've just watched Andrew Marr try and stitch him up which is probably the soft version of what's to come so it's not going to happen anyway
