@miniature-megabyte-70920 What you describe sounds really screwed up.
1. It doesn’t sound like you can push back or influence enough to make your job reasonable.
2. In such situations, probably best to pursue other work (whether freelance or staff), at whatever pace best helps to maintain your mental and physical health, as well as financial situation. That can be tough to balance, and you might have to make painful trade-offs, which blows. You have my empathy on that front.
3. Something to consider for future: Try to build a fuck-you fund, so that you’re better able to walk away from untenable career situations and have breathing room to land other work as needed.
Early in my work life, I took side gigs and scrimped like hell to build such a fund, because I didn’t want to be at the mercy of assholes or other screwed-up people. (I worked in news, an industry that often treated people badly.) That, plus living under my means, was always important to me, even when I made little at the start of my career. That’s because you want to preserve and build as much power as possible to live and work on your terms.
Such a fund not only can help extract you from bad scenarios, it can give you greater confidence to negotiate harder for new work in various situations.
Everyone’s circumstances and priorities differ, of course. Sometimes, you might not feel like you have much agency or control, but it’s crucial to recognize that you do, for your own sake. And you have skills that others will value.
Good luck! Rooting for you!
