I'm leaving because:
My desk is far too high, nearly at shoulder height. I go home every day with wrist, elbow, shoulder, and back pain. I'm 30 and this has never happened before in previous offices or when I worked from home in my last job. The monitors have built in, non-adjustable stands, so they sit another 6 inches above the desk so the bottom bezel of the monitor is pretty much at eye level. This causes neck strain because I'm looking up all day.
The office is very poorly lit with no windows and almost no indoor lighting.
The company has immediately shut down any suggestion I've provided, like a lamp for my desk area, a higher office chair, a cushion for my chair, etc. and would not let me bring in a cushion because they said it's a "safety hazard" because I could fall off the chair. They said I could purchase my own office chair and they would "test" and approve it downstairs, then I could bring it in. I thought that was fine. (I'm also not allowed to work from anywhere but my desk.)
Then I looked at the price of an office chair. Then I started looking for a new job. 3 weeks later, I've accepted an offer and will give notice tomorrow (Friday). It's been 5 months. This will be my first short stay in my career.
Except for these issues, the work is fine, the people are great, my boss is fantastic, etc. and I wouldn't be leaving. But this isn't sustainable. I'm resigning for ergonomic reasons and ideally I want to explain this at the exit interview, so they know it's nothing personal, and hopefully they will take action for others if they see that someone is actually leaving over it. Since it's nothing personal, is it professionally safe to explain my ergonomic reasons or should I just keep it vague like "it's not a good fit"?
