Treated no better than a Walmart worker. My heart goes out to you. I have made it a life mission at my school to give adjuncts interviews for tenure positions if I am on a hiring committee. Even then, there is resistance. That makes my blood boil.
I wish I had solutions to offer. Perhaps more pressure during accreditation reviews would help. I read on DU someone posing the idea of contacting US NEws and asking them to include the percentage of adjuncts when ranking colleges and docking them points. Give them real incentive to stop this abusive practice. The situation is critical. I wonder if adjuncts should stage a nationwide walkout? You need to draw attention to the problem. You are hidden away. I call you academic migrant workers. You deserve better.
Unfortunately, college admins everywhere want to eliminate all tenure jobs and turn everyone into an adjunct.
I remember at the college I attended, they had a seven year rule. Anyone hired to teach that long had to be considered for tenure. I imagine this was an attempt to address the problem. Instead, the best instructors always lost their jobs that 7th year. It's an ugly system. Colleges should be ashamed.
