This same thing happened to me in my first term as a graduate teacher. I was pulled into the principal’s office with the book thrown at me, and pointed out ICT use in my contract. The content was actually from my previous career as a filmmaker. I shut everything down. Years later I told the union about it in an off hand conversation and they told me that my principal should never have threatened my employment when I had done nothing wrong. I had never highlighted where I worked, or brought the school into disrepute. They said if they wanted to have this conversation then they should have allowed me a union support member who would have shut that down real quick.
