My knee forced me to retire also. I had planned on working till I was 62 because our pension gets a 6% per year bonus for each year worked over age 60. I was going to wait till I retired to get the knee done. Then I tore the retina in my right eye and missed 5 weeks of work. Was off job so no comp. I was a shifter moving trailers in the yard. When I came back to work I was informed that once my bid run had gone 30 days open, they could cancel the run. They put me back to work inside sorting packages. Same pay but no overtime. I was getting 15 hours a week OT shifting. After a few weeks inside, working on steel grates and concrete, my knee got so bad I couldn't wait. It's been a year and 3 months and I can only get about 100 degrees on my bend, but no pain. Now the other knee is as bad as the first, so I'm looking at getting it done this year, Joe.
