Honestly, I've enjoyed teaching at Grantham. Adjuncts are not the highest paid but neither are they the lowest paid. I've never felt pressured at ANY time to lower my academic standards. However, they do create the class for you and while you can add to it you are not allowed to change it. and some of my current classes need changing. That said, I've been able to make recommendations and have seen them implemented. I've never been hassled because too many students failed; I do expect students to do the work and I grade them fairly. If they fail its almost always because they failed to turn in work but sometimes they are just not ready for college.
I've taught at three public universities and at least during my most recent experience at the public university, it was very clique-ish. Everyone was trying to climb the ladder and if you did anything different, you were out. They claimed academic freedom but I did not have it.
I could be quite happy teaching here for the rest of my professional life (hint, I'm not very young...). I know my subject, enjoy adult students, and genuinely look forward to sitting down in front of my computer in the morning.
If you are happy being an adjunct, it can be great.
Not the highest paying position
