They always gotta have a coach....
I graduated as a Phi Beta Kappa Junior inductee from UNC Chapel Hill with a degree in secondary social studies education over 20 years ago now. I was first in my education class with over a 3.8 GPA. I had stellar reviews from my student teacher experience and LOVED being in the classroom. I had excellent character references. I was pumped, psyched up and ready to change the world..... I'm also not a coach.
I interviewed for MULTIPLE highschool teaching jobs. In EACH interview one of the first 5 questions I was asked was not about my philosophies about teaching, not about my academic career, not about my student teaching... it was 'Now, what extra curricular activities can you coach???' My answer was always, 'I am not qualified to coach any sports, but I'm certainly willing to assist or to take on any clubs, etc"
Sometimes the principal was nice enough to cut the BS and ask that question first. The interview was always over very quickly after they heard my answer. And a couple of them were even nice enough to admit that I was a GREAT candidate for the position, but they needed someone who could coach _______ (fill in the blank here - football, soccer, basketball, etc.)
I did end up getting a job - as a 10th day hire completely out of my certification area (middle grades SS/health/PE, ironically enough). I was miserable - it was totally NOT where I wanted to be - wrong subject matter, wrong age group.
When my job ended at the end of that year due to the population dropping at my school, I did the 'can you coach?' interview circuit again the next summer trying to move back into High School Social Studies with the same results.
Ended up getting a job teaching at a community college part time and eventually moved into corporate training.
Because they wanted COACHES and not TEACHERS, they lost me completely. I'll never go back into the public school classroom, although I think I'd be a better-than-ever teacher now that I've got life experience as well as a good education.
I have no doubt that in your case that was the decision they made - they could keep a mediocre teacher who could coach or keep a good teacher and lose the coach. When there's a hiring freeze that would make replacing the coach next to impossible...they made their decision and you are the one who pays the price.
It's all about the priorities... academics will lose out to athletics at the high school level most every time - at least in my experience and observation.
So sorry you are going through this - hope that a silver lining appears for you very soon!
I have to say that I wanted to teach so badly, but I ended up with a much lower stress job where I make 3x what I would be making if I were still in the classroom. While it hurt so badly at the time - the disillusionment of my dream career - in retrospect losing my teaching job was truly a blessing in disguise and one of the best thing that ever happened to me. I still get to teach through my job and in the outside interests I have without all the stress and BS you have to deal with in a public school classroom.
Good luck to you! I hope you have a happy ending too!
