I'm not surprised.
I previously worked in a well known global bank. They operated hybrid working during covid, but the expectation once covid was over was that if we wanted to work from home, it was pre approved and not every week.
We worked extremely long hours - 50 hours a week minimum was the norm. Eating lunch at desk. I took my hour long allocated lunch once and manager was ringing me after 45 mins asking where I was.
I am a single parent household and I became stressed and exhausted. To top it off, despite working my ass off for 4 years I was constantly being passed on promotion in favour of the managers friends.
Last year, I decided to go on sick leave before I took a psychotic break. I was drinking heavily to the point of passing out, I was miserable and tired all of the time.
I took 3 months off sick and in that time, I secured a new job with better pay. I went back for two weeks notice then left.
I wanted a bit more time off to recover emotionally but I didnt want to pass on a great opportunity. I took myself on holiday on the last week of my sick leave and spent it relaxing.
It was the best thing I ever did.
If the NHS made mental health services more accessible, there wouldnt be this situation. I paid out of my own pocket (around £2,500 for sessions overall) and just going to them made me decide that my job was NOT helping me and that I needed a change. Having third party input was definitely needed as my family etc were all telling me to stay in my "secure" job.
I now have a flexible working job which is hybrid (WFH 80% of time) and is paid more.
Companies also have a lot to answer for to how they treat their employees.
