This policy should not surprise anyone. In business, a single remark can cost your job. Likewise a teacher who does not understand how easy it is to say something offensive in class will be criticized by those offended students and will be censored for it.
I used the expression, “whatever” and I cannot even remember the context but my advisor cautioned me to be more cautious in front of the class.
I was not teaching a social science class, it was a lads in beginning electronics, but I became more careful, since the depth head was taking a special interest in me.
Depth head ???
Department head maybe?
