Can they force me to opt-out of WTR?

[fraggle08]

I've been offered a great new job but the contract includes a section about opting-out of the Working Time Regulations of 48hrs per week. By signing the contract, which I obviously have to do, I automatically waiver the WTR. I'm suspicious about why they've included it, as the job shouldn't require long or unusual hours.
I'm not adverse to hard work but like most office jobs they don't pay overtime. In the past I've had jobs where it was expected of me to work very late every night and I did it, but escaped because it made me crazy!
I don't want to go back to that sort of culture but I feel awkward asking them about it as I don't want to start off on the wrong foot!
I have heard that a lot of companies just automatically include it these days and may never actually require you to work past 5.30!
Does anyone else have experience of this, or advice? Most WTR opt-out discussions I see on AB are Pro, from the hourly rate point of view, which is great but what about the other side???

The law is quite clear:-

If you want the job just sign the opt-out anyway.

You can cancel your opt-out ay any time in writing with no more than 3 months notice needed (less if your employer agrees).

You cannot be dismissed for 'changing your mind' or be treated detrimentally within work because of your actions.

That is the theory..........and the law..........not necessarily what happens in practice.
