I had a similar situation with an employer. Went on mental health leave, came back to multiple brand-fucking new disciplinary actions, constant new barrage of changes, I disclosed my medical conditions and it got worse. Until I literally snapped. Couldn’t work, couldn’t function for 7 months after and I’m still not recovered.
And don’t get me started on what their messaging was about mental health.
Fuck all the talk, fuck not having room for humanity at work, fuck depression, and fuck bad things happening if someone’s brave enough to try and get help.
