This week's cover feature on "bedblockers", those irksome colleagues who coast along for years without being any good, shows just how difficult it can be to remove teachers who are underperforming.
But a recent thread on the TES Connect web forum has unearthed some even stranger relics from a time long before the General Teaching Council even existed. Back in "the olden days", to which the posters fondly refer, one science teacher turned up to a disciplinary meeting preceded by a remote control car.
Another teacher remembers a chemistry teacher who would disappear into a prep room during lessons to smoke a pipe. One remembers an ICT teacher who was so out of touch with the syllabus that he refused to introduce the internet at school as "the kids would never understand it".
These experiences clearly haven't put off our then newly qualified teachers, as they are still in the profession today.
