Hey folks, first I'd like to say that I'm about as brand new to this forum as they come, but it looks like everyone here is friendly enough

Anyway, I'll briefly fill you in on my situation. I just graduated from the University of North Carolina - Chapel Hill in May with a BA in physics. For the past 5 years, my dream has been to teach high school math & physics.
However, I must say that I am pretty upset with the way education is run and how teachers are treated. I spent all summer scrambling to find a teaching job in my area, only to have that job
given to someone else in the district after convincing the principal to hire me. In desperation, I managed to convince another principal to hire me within the next 48 hours. 10 days later, they are still trying to get everything together to hire me while in the meantime, there is a sub teaching my classes who is teaching them absolutely nothing (I spoke with the sub myself.)
Tonight I ran into someone at Arby's who told me that he had come out of retirement because they are so desperate for qualified problem solving type thinkers in nuclear plants. I met him because I happen to live only a few miles from one in NC. He encouraged me to at least consider it as a career for several years, and I don't see any harm in it since I can go back to teaching science & math pretty much whenever I want to.
I was always under the impression that a physics degree was WAY inferior to, say, an engineering degree for this line of work. He urged me that it's all about on site training anyway, and that a physics degree shows that I have enough problem solving skills for them to hire me in some entry level position. He also told me that there could be a possibility of later on working mostly with training others in the field, which would allow my passion/talent for teaching to really shine.
Is this really doable? Is the demand for mathematically inclined workers as desperate as he makes it out to be?
I look forward to hearing what you guys think! Thanks for reading
