Decent job - Sortation Associate Amazon Employee Review

I worked at Amazon warehouse for 1.5 years as a seasonal worker. It wasn't too bad. My main issue which caused me to resign was the fact that I was and I never converted over to become a blue badge. I never became permanent even though I had a great employee record. I wasn't written up or anything. However, what's the point of coming to work if I'm considered a seasonal employee and I can't comvert. There were employees there who were in the same situation as I was. There weren't any opportunities available to become permanent. I can't keep working if I can't get the benefits of the full time permanent people. I became resentful and angry of this issue so I got another job and quit.
