sorry guys, i sorted it now.
it was to do with a new contract of employment at work, its and extremely vague contract, and gives the company complete control of my life if they so wished.
it states that in signing the contract i am agreeing to work any time between 8am-8pm 7 days a week, and i have to in the interests of the company, if they so wish, work more than 48 hours per week, i can opt out of working over the 48 hours by giving 3 months signed and written notice.
although it does say that i can have time of in lieu, it is at the managers discretion. so if the manager wants to be an arse he can.
so i spoke to acas, about the complete vagueness within the contract, and i have no option to sign.
