Seems a bit weird!A secondary school is to allow pupils to swear at teachers - as long as they don't do so more than five times in a lesson. A running tally of how many times the f-word has been used will be kept on the board. If a class goes over the limit, they will be 'spoken' to at the end of the lesson.
