We get 32 days + public holidays, so you could take something like 7 weeks off with careful planning. Most people do. Because most people do, it isn't looked down upon at all.

A friend at a US firm said they told him if someone could take 3 weeks off then clearly the company didn't need them and there wouldn't be a job to come back to. Here it wouldn't be anything unusual at all.

I took 26 days leave last year (4 pre-Covid), and carried over a few extra. Even with Covid, there were opportunities to take trips locally, or just have a day out of the house with no obligations. I used a few days to work on hobbies when friends were working.

When it's use-it-or-lose it (or, in my case, use-it-or-be-forced-to-use-it-in-crap-weather-December), why work?
