I got tenure. Next I was promoted to full professor (but not without a fight). But everything has become about our new hires and what is trendy and cool. The fundamentals are not being taught. And there is no building of skill sets. This meant I never knew at what skill level students coming into my classes would be. This doesn't seem to concern anyone else, and I care only because it negatively impacts the program I worked to make successful. Yes, I'm open to change - when there is a reason for it and not simply for the sake of change itself. And not just because our newbies like making me feel out of touch (I assure you I am not). I found myself being told I couldn't teach this or that. The reason? I was told there were budget constraints, when our budget could more than accommodate my reasonable requests, and without impacting the needs of anyone else.
I don't actually qualify for retirement. But I was weary of being treated badly and tired of watching a successful program suffer. I went to our admin and said, I have a simple request. I'd like my colleagues to actually listen/consider what I have to say and behave in a professional manner OR make me an offer regarding retirement. They chose the latter, which is a sad statement of how the university approached such concerns. I worked hard, and was very dedicated.
So I have moved and set up an office where I will work on weaving hamsters. Well, not really, but you get the idea.
