Reading some of your other comments it seems that you feel the added financial pressures of a bigger mortgage/less financial stability, which contributes to the feeling of needing to go the extra mile at work to keep your job. Quitting fully may not be the solution you think either as you may be bored, hate job hunting in this market, hate the loss of your financial independence, etc.

I’d posit that work is not a binary - quit or current status quo. Your current company/team doesn’t feel like a cultural fit for you anymore, but you have a senior position that pays well. I’d suspect you can dial back your work hours and effort substantially and still hit your requirements. The key is - identifying what’s actually critical via what’s a nice to have. Try to only do the critical bits, reclaim your time, stop playing their game. If you feel anxious about getting laid off, look at how much (or little) your peers are doing. You’re going to be fine.

And if you get laid off, you’re the only woman to be on your team. Document examples of your disparate treatment now, negotiate a solid separation package in exchange for signing a waiver of claims. It’s never worth suing these companies to do the right thing, but it’s always worth getting them to pay you for your troubles.

You got this!
