Same here. Teach in my subject of qualification because I enjoy teaching.
I tried that. Despite the much bemoaned lack of teachers in science and math - and a M.S. degree - I was told (in California) that I needed a degree in “Education” in order to teach High School.
Sure, as a Graduate Student I was apparently qualified to teach College students University level Cell and Molecular Biology (I was very highly rated by my students), I was apparently unqualified to teach High School students basic Science.
I loved teaching as well, and was willing to take a pay cut to do it. But I was not willing to go back to school to get a degree in “Education”. My ex wife went through that and I helped her though the nonsensical course work.
But all is well that ends well. Now I do real science every day and make more than I would have as a teacher (although the work is harder and the hours longer and the perks less). Moreover I really do good with the work I do - finding life changing novel treatments for serious diseases.
When I hear about them threatening to strike I can only think “Ronald Reagan and the Air Traffic Controllers”.
Fire them all and replace them - it shouldn’t be too hard to find qualified teachers if you do not insist on a degree in “Education”.
