Harold "Harry" Potts was a corrupt councillor and school caretaker who made an enemy of Alf Roberts and Derek Wilton. In October 1992, Derek Wilton became the new deputy caretaker at Weatherfield Comprehensive, under Harry. Headmistress Sue Jeffers gave Derek the job instead of Harry's nephew, who had been Harry's choice. Harry deliberately gave Derek a hard time by demeaning him and making him do most of the work while he skived, using council meetings as an excuse. He also caused Derek to get into trouble with teacher Ken Barlow by instructing him to throw out wallcharts when clearing a classroom and then denying doing so, letting Derek take the blame for the loss of a month's work. Derek reported Harry's bullying behaviour to Sue Jeffers (as Harry was the union rep as well as his boss),
