My boss/team leader/other manager would just laugh in my face if I said I couldn’t attend meetings or asked to have them moved because of swiss cheese or something
2. You have to actually try it to really know if that works or not
3. It might not stick the first time but if you do it a bit more often without being forceful (just asking "is there a time that would work in the afternoon too?"), then it might lead to a better outcome.
Overall, frame it as a gain for the company, not for yourself.
Some can be done to change company culture to reduce and optimize meetings, of course. Hopefully.
"I need a big chunk of time to do my job well" sounds very different from "attached is my list of demands".
