Hippy – if you have been informed in writing that your position is definetely being made redundant, but they are keeping you on until the final day of employment (the alternative being called “gardening leave”), I’m sure that you cannot be prevented from taking time off to seek alternative employment.
I.e. it’s not like going for a job interview when in normal employment where you have to take holiday. Because your position is being terminated the rules change. More info on the DTI website here:

If one of your managers won’t talk to you, then that’s his personality issue, not yours. Fuck him. (Erm, figuratively, not literally!).
What I’m trying to say is that if your life being made hell at the office is preventing you in any way from seeking a new job, then you have your employers over a barrel and can legitimately complain. You may be able to get better terms, or perhaps immediate gardening leave. Or maybe even treated like a human again.
