I'm on un-official all out, and yes I was told the same as you. My contract states that some elements of my job are required to be undertaken out of hours, and I will receive time in lieu in return. Problem being, I'm too busy to take my lunch hour and holidays, let alone any time in lieu. So the hours build up on my spreadsheet, and I have been refused payment in return.
I have to use my own mobile, but I switch it off when I'm asleep, otherwise I'd never get some kip!
Hmm, this sounds worryingly familiar. Our contracts are very basic at the moment and quite vague about working hours as it is. I'm already coming in way before my start time to set up every day and cant remember last time I had lunch, but up until now it hasn't bothered me because it's commensurate with my position.
I think any assumed OOH work without compensation would be taking a liberty. To be honest I'm not that keen on doing it anyway with things going on in my personal life, but could always do with extra money and want to try to remain professional.
