Mytholmroyd - I agree: it's also often men who are bad at admin, and get away with it because they twinkle charmingly/ruefully...
My department has those who can always be relied on: and we are the ones who get dumped with stuff, because the HOD knows it will get done. But the alternative to doing it is that you know someone else with to much to do is going to get screwed over.
Deianira I don't want to depress you, but I've been in post for just over 5 years (in a university where we don't have sabbaticals and research leave has to be covered by external/grant income, despite all staff being expected to submit at least 3* submissions for the REF): it gets worse after PhD. If you're humanities/SS, you'll probably go straight to TF for a year, because the people you're against now for entry level lectureships have at least one book published already, and no matter what the JD says, that's what the recruiting will be done on. I TF'd for a year - and because of the teaching PG Cert, had to log all my time etc (a habit I still keep): 9 month contract (until late June) average 120 hours/week, 7 days a week all through (except for Christmas and Easter days; no time for conferences, writing or anything else, because of writing all the new teaching materials for my modules, plus teaching, admin, seminars, pastoral care, meetings etc etc
Then, if you're lucky, like I was, you move to your permanent job: first few years exactly the same as being a TF, because you don't inherit any teaching etc, so preparing all your lectures, materials, classes - plus bigger admin responsibilities, because you now also have service at department, school, faculty and/or university level. First three years, I worked an average of 100 hours a week (same two days in the year off); after that, things got better, because I got the hang of how things worked, argued for a more reasonable work load, and more staff were taken on etc After that, it's seven days a week and weekends until the end of teaching and exam boards: but the summers have got better, once you allow for the endless meetings and appraisals, and bloody, bloody Clearing, which in our case, we don't need to enter, ever, but our HOS insists we do because he thinks it makes him look good if we over-recruit... In practice, then, that's about four weeks per year that I can count of for concentrated research time. Average working week 70 hours in term-time, 50 outside.
In five years, I haven't been on a single date - don't have time; a single holiday - ditto; used all my leave - are you kidding?! When do you think I do research?; made a friend outside of work in my (new) city - why would I? I don't do anything except work.
Someone said they envy us lower down the totem pole with the time to read books: hilarious! I have a pile of journals on my desk about 3 foot high where I've been putting them for when I have time - it's one endless firefight.
In fairness: we have a lot of very unreasonable expectations on us (post-92 going up in the world, but without the wit to realise that other things need to change if we are going also to kick research arse); excessively poor middle- and senior-management; an exceedingly challenging student body, many of whom lead incredibly chaotic lives and have very difficult circumstances, so pastoral issues take me at least 12 hours a week to deal with.
I wish you luck - but it's not a bad idea also to be realistic: and unless you're in sciences (in which case, you have the first round of the post-docs, which weeds out some, the second round, which weeds out others, and then the lectureships, which culls much of the rest of the former student body) you are unlikely to easily meet your future DP. If you're fine being married to your work, as I am, that's not a problem - but if your heart's set on marriage and children, you might want to consider your options. (In my building, where about 200 people work, there are 2 single men, of any age: our male colleagues have a traditional propensity for marrying their students :-/ By contrast, we have quite a number - well, 6 - of happily single women)
Phew, long post: can you tell it's my no work weekend day :-D?
