Ugh, I know that feeling, my last job they said they cared about my back and would send the 'guy' out to fix my chair for me when other people had re-adjusted it, then they wanted a Dr note, then they had a big meeting with some of the managers to ask if I really should be at work (very intimidating) and on and on. My Dr was a 'good guy' and sent me for scans proving I had a 'real' condition that needed to be considered.
So when my Dad needed me to help him out I went--- it got passed 'nuts' !!!
Hope there is some position you can do that won't put you in harms way Ken. You have been through so much. 5 days ago
