When I left teaching, there was a political tussle going on, and the administration had been unhappy with me over my work as the Grievance Chairperson in the district for the last few years before my retirement. I had represented a bunch of teachers, and I never lost a single grievance. The last two years, I gave up that position, and apparently the administration saw that as time for "payback."
In the end, the principal trumped up a letter to place in my permanent file. Upon my retirement, the district presented me (and the other retirees) with a plaque for service. I told the principal that if she really wanted to honor me, she could remove that ridiculous letter from my file now that I wouldn't be there to challenge them any longer. She said no. The plaque remains unopened in my office here at home.
I did not go to the Retirement Dinner the district held for us retirees. Instead, I visited my sister in Connecticut that weekend.
I loved teaching; I loved the kids; I hated the administrivia.
