I've mentioned elsewhere that a father wrote to me, threatening to report me to the Director of Education for phoning his wife at work, to say that their child was ill. (Said child was lying across two chairs moaning "Oh, my belly!" They should have been in a mock exam. The yells were enough to waken the dead.)
We couldn't take any chances, so I'd phoned the first emergency contact, the grandmother. No answer.
I'd phoned the second emergency contact, an aunt. No answer.
I then tried phoning the father at work. No answer.
As a last resort, I phoned the office at the mother's place of work and asked them to pass on a message. This, apparently, was outrageous behaviour.
The mother was a teacher in the feeder primary 10 minutes away from our secondary school. I had phoned the father before the mother precisely because I thought that it would be more awkward for her to leave her class than it would be for the father to step out of his office.
I recall that both my HT and area union rep found it hilarious that the parent seriously believed that the Director of Education would report me to the GTCS for unprofessional conduct.
