Don't they have to give you some form of reasonable notice, get you to physically sign a new contract with these new hours before they thrust them upon you?
Luckily on my end it's just the overtime that's been cancelled. About 18 hours worth, which when working 25 hours a week trying to save for a mortgage deposit is a big hit. We all think it's the tram works going on in Beeston crippling the business.
Another sexy Tesco moment is we all got a "personal" letter from one of the heads of Tesco asking us to fist the Price Promise shit to EVERY SINGLE CUSTOMER. I'm pretty sure everyone knows by now what it's about. But the amazing thing is in the second sentence - "When I'm shopping with my wife at Sainsbury's or Marks and Spencers" = fuck my own supermarket, I'm going to the competition.
