You really need to look into this and start taking some action. First, you cannot have been overpaid under the protected pay rule. Yes, its your Oct 2004 pay that is protected, but any cost of living / length of service rises have been factored into that, and you have starts a new job, it is the starting salary on that that is protected. Secondly, all annual leave is also protected. So, if you are entitled to 27 under A4C rules, and are currently on 30, you will stay on 30. If, like in our trust, you're on 21 days, you jump around for joy and the management panic over all the annual leave everyone will have next year (as that is also back dated to Oct 2004) I am guessing (I'm sorry), that the rumours about tiny pay packets are simply that, rumours. I'm having to look into this an awful lot as my manager is being royally screwed under A4C, and needs to know exactly where she stands (she is being banded 2 grades LOWER than half her staff!!). If people have lost anything over this, then your trust has completed screwed up, and you have to appeal it within 3 months. If the union won't help, you can take it to tribunal through your local SHA (North East London SHA for you I think http://www.nelondon.nhs.uk/ though I get confused with the ambulances). Again, you have 3 motnhs to start this process, and it is probably good to get ACAS involved too. Unfortunately, if its more than 3 months since you received "the letter", then you will be getting into harder territory as thats when you're meant to start these processes. People power does seem to be working though. Entire professions joining together. My trust is close to losing every single member of staff in one certain area, and if they did that, no patients could or would be treated. Hope there is something useful in all of that.
