I don’t begrudge extra time, but I claim it as time off in lieu/overtime, without fail, and it’s my time- my terms. Doesn’t seem that controversial but it came as no surprise to find that the sort of boss that expects you to work extra hours is also often the sort of boss that expects to not pay you, or ask you, or ever give you time off in return. The same sort that reacts with horror if you ask for a day’s holiday.
The bottom line is you’re paid to work, and that’s not a good link to break. If you expect people to work without pay, you can’t exactly complain if you pay people and they don’t work.
What I found really interesting is the people that say they “have to” work overtime, and that they can’t claim it. A colleague of mine in my last job in the bank couldn’t be convinced this wasn’t true- we were all either clocking off at 5pm, or claiming the overtime, she was working early every day, taking short lunches, and never claimed a bean. And what was weird about that was that she was really aggrieved about it. How dare they make me!
