For all those who are saying they are overworked, and listing long lists of responsibilities, I completely hear and respect you. HOWEVER there are a lot of work shy lecturers in senior positions who do the minimum possible.
Actual things I've seen:
Second marking - read the first sentence click next approximate time to second mark one paper 20 seconds. Leave a comment occasionally so it looks like you've done work
Department meetings - 'attend' via teams, make zero contributions, do whatever you want whilst meeting is taking place...like head out to play golf?
Course planning - update name of prime minister on slides so it's relevant keep everything else the same as previous year.
Exam marking - a LOT of work, but done during the summer so don't need to be on campus and no teaching responsibilities
PhD students - currently supervising 2 students, one is dropping out. Drops them and email every few weeks to see how they are getting on.
1 to 1s with students 10 x 10 minutes appointments twice a year
On campus 2 1/2 days a week for teaching and seminars
Admin tasks - just doesn't do them. Hes been there so long that he is 'untouchable'
Outside of work does media appearances, has published numerous books (some with upfront payment from publisher), many editions of the same book with a few tweaks (so minimum work max payoffs), plays an obscene amount of time playing golf during the working week.
Salary 50k.
I think it really depends on the university and where you are in your career. One person's experience doesn't reflect all senior lecturers. Some are hardworking, inspiring people who care about their students and work long hours. Others are work shy and do the bare minimum, just like in any profession.
Overall I believe everyone in the education sector is underpaid. And more need Sto be done to weed out the twerps that gives the profession a bad name.
