Really surprised by those of you who reckon a 4 rated department is just as good an envt to work in as a 5, my DH would definitely disagree. He is in a 4 dept at the moment having only worked in 5 depts previously and the difference has been huge (Thank God he has a new job in a 5* Dept).
In the 4 rated dept the average lecturer has 40 hours teaching a year, in the 5 it's 15 hours. The 5 rated department has research council funded and industrial sponsored PhD students who are GOOD, the 4 department takes on overseas PhD students who are simply not up to it and who generally take longer than 4 years to complete (to the point where the dept has so many students exceeding 4 years that it is now ineligible for studentships from some research councils).
At the 4 rated department they have to record every letter they send out, charging it to grant accounts where possible, there is a stationary allowance and once you've exceeded your allotted amount of paper you have to buy your own....
This is in a relatively rich Russell Group University. I also work in HE (at the centre) as an administrator, this Uni has an entire faculty where no dept is rated over a 4, we have a university wide early retirement policy to get rid of the daed wood that is strangling the departments. In the mean time those depts are basically "bums on seats" and some (e.g. Sociology) are being earmarked for closure-amalgamation.
It sounds as if many of you are in more Arts/Social Science based areas? DH is a scientist so journal articles are turned round in a matter of weeks (even for the US journals) so publications aren't a problem.
Have to say though that as an escaped academic the attitudes of some lecturers are truly crap and I think it ends up with "The centre" getting frustrated by a few people and then coming down heavy on everyone.
