Ha! This sounds like me two years ago when we got our new principal. Our first staff meeting he told us what we had to wear and what kind of shoes. It was the first week of August and was in the 90s. We have no A/C in our school, except the principal's office. I teach in an inside room with no windows, so by law they have to bring the air in from outside. They pull it from the roof over my room - so if it's 100 on the roof, it's 100 in my room. If its 50 on the roof, it's 50 in my room.
That afternoon I went in for a pre-year meeting with him and he asked if I had any concerns. I explained that my room gets over 100 and that in the past I've been allowed to wear shorts. He said absolutely not, that it was dresses (umm no, I am up on a podium when I'm conducting) or the slacks he had shown us examples of. No shorts, skorts, or capris. I also explained that I had nerve damage in my foot and the shoes he told we had to wear were not something I could wear. To bad, so sad!
I tried to follow the new rules. I really did. Several times I invited him into my classroom so he could see the conditions. No go. Then I started breaking the rules. He wrote me up. I signed. I continued to break the rules. He continued to write me up.
One day I was wearing my Hoka running shoes with the approved slacks. In comes Mr. Principal with guests from the state department of ed. They've been in my room before and have seen me teach. Principal has never seen me teach. One of the guys comments on my cool shoes. He runs with them as well and loves them. Mr. Principal makes a comment in front of my class that I'm a rule breaker and he's written me up several times because I can't teach and breaks the dress code. I was really mad!
How did I solve the problem and keep my job? Two things- the parents of the kids in that class were crazy mad and let him know it. Second, I went in to my doctor for an ear infection. I told him why my blood pressure was off the charts. He wrote me a prescription that said I was allowed to wear any shoes that I needed due to the nerve damage and that not allowing me to wear clothes conducive to the classroom conditions was dangerous and could be grounds for action. Mr. Principal took this to high admin and they told him he was not going to win this war with me.
Guess who will be back at our school for her 27th year and guess who won't be for his third year?
