I'm less worried about although changes to your working contract are more likely through that. breaks/overtime companies already take the **** but for most work have a required amount of time is important. Plus enforced overtime is not good for those wanting a good work/life balance.48hr maximum working week, what's that?
Everyone starting a job that is anywhere close to 48hrs a week has to sign an opt out. Otherwise they either don't get the job at all or other barriers suddenly appear, like the requirement for detailed daily timesheets.
My main worry is firing laws especially in the current economic climate. It's a **** to get rid of people (who have been working for you for 2 years) but it protects people massively financially combined with redundancy laws. People in general could get royally ******.
