Terrible culture - Buyer Saft Employee Review

I had been working at SAFT for several years when I started having terrible back pain and spasms. My manager had recently been replaced and the new manager was very unsympathetic of my health issues. She told my coworkers that she thought I was just being lazy. When I found out that she said I was being lazy I was actually walking with a cane because my back was so bad. At this point I was 33 years old. Even though, every day that I couldn't drive due to my back pain I offered to work from home I was included in a mass layoff. The GM was very kind about it but when I reached out to my coworkers I was told that my layoff was directly caused by the manager not believing that I had any health issues. I also found out later from multiple other people in management that she had been going around telling everybody that I was a lazy person who was lying to try and get out of working. I even had to go to pick up my phone charger and was treated like a criminal, my old manager told me I wasn't welcome on the property even though I had literally left on great terms with a severance package. I later found out that all of my back pain and back spasms were due to four tumors growing on my spine and one in my hip. At my diagnosis I was given about 2 weeks to live without treatment or 5 years possibly with treatment. I have luckily beat my cancer for the time being but honestly will never get over how terribly I was treated by this company at the end. Prior to this on every yearly review I was given glowing remarks and a raise each year. I was constantly praised by even those outside of my department for reaching out and helping any time help was needed. I constantly volunteered myself for things outside of my purview like training other departments on purchasing processes, running inventory at year end, etc. My experiences before this were decent, my prior managers had been very kind, I got along very well with the rest of the staff including the GM, but the way I was treated at the end is unforgivable.
