I'm going to assume your work requires your physical presence on that ship, in the deep sea, though. My work, however, does not. Further, employers are, on the whole, cheap, and want to pack workers into as small a footprint as possible. (Literally, 4' or less.) I can build a better work environment at home, for under $1k.

"My [unrelated] job is worse" is not a logical reason for me to abstain from advocating for better work conditions for myself, where there is a possibility of better work conditions. I can dislike things about one tech job vs. another tech job while still appreciating that the conditions of either job probably far exceed that of a career I wouldn't like.

(And, I would also still default to advocating for sane worker's rights in your industry too, unless there is some compelling reason that working >8h/d, 7d/wk makes some sort of sense in your industry.)

Sounds like a prison work camp!

"You kids think you're being exploited? Haha that's nothing, I've been exploited 10x harder!"

Let's not crab bucket each other. You deserve good working conditions and making life suck for everyone else, too, won't make your life truly better.

"you should feel good about that because my life has been much worse"
