That said, certain positions can be difficult to fill depending on location and/or a lack of willingness to move. Each year, there are music ed graduates who do not get a job for one reason or another. Those who are not band directors can get jobs much more easily.
The reason people are leaving? I suspect you know the answer already. I think the question we should be asking is: how can we get the *right* people in the profession and how do we keep them? Ultimately, every single teacher *is* replaceable, and unfortunately, many leave the profession either because it was not what they expected and/or they were not put into a position to succeed.
The pandemic was interesting -- we had a brief amount of time of great appreciation for what we do when they no longer had in-person school. But that was short lived.
I *hate* being political, but I wonder how much progress would be made in K-12 schooling if politicians focused on that instead of college debt? K-12 is compulsory and I would argue much more important and relevant to the majority of the country. But what am I to say?
