Dress codes definitely exist, even if they're usually not stated.
I'm a woman. I also have MS. A lot of people with MS, myself included, experience something called the 'MS Hug', which is spasticity, pain, and tenderness in your ribcage muscles.
Wearing a bra for 9 hours a day ensures that I'm in a shit ton of pain. A full time RTO job would mean being in pain constantly so that other people aren't offended by my body. Right now I'm hybrid with one day a week in and I just load up on painkillers and muscle relaxers for that day, but even then I can only do so much because you can't just down 8mg of tizanidine and then drive home.
You wouldn't know any of this by looking at me.
Hat tip. Thanks for the honest reply. First hand accounts like this make HN a better place. I'm sorry you need to suffer from that. I wish you luck finding a job that will allow you to do 100% WFH!
