So if you are rostered off on a bank holiday you also want a day off in lieu! Can't see that happening.
Happens where I work.
Think about it. Day workers, IE those that only work mon-fri get ALL their bank holidays off plus theIr statutary (minimum) annual holidays. 8 bank holidays plus their holiday entitlement, 25 days in my company I think.
Now, as a shift worker, I may or may not be rostered on shift during a bank holiday. Therefore I get 8 lieu days (as there are 8 bank/public holidays) to use as and when I can. I also get my annual entitlement of 22 days (cos I work 12hr shifts).
My employer also calls a day a day. Non of this 1.5 days for a 12hr shift off nonsense.
