zero, pretty much the same here. if they were to change my contract to the irish system, then i'm offski at the first opportunity.
As for reaching the 5 years, it just continues rolling. They don't change it or enforce another one. You always hear a lot about BRK doing this/that, but in reality, its all rumour. If they changed contracts, or made guys sign new contracts on CU, or base change, or the new contract to change base etc etc, then you would hear about it. It's all rumour and they pretty much leave you alone but you can never say never. If they wanted to enforce change then I think they've missed their window of opportunity as the market starts to swing towards the workforce.
