Alf Clayfield, a 22-year veteran with the Waterloo Region School District
, convinced a labor arbitrator that a drug he was taking as part of a clinical trial for arthritis caused side effects that were partly to blame for his outburst, the story stated.
According to the story, Clayfield became irate, threw a chair at a door and hit his area supervisor in the chest hard enough to cause bruising when asked to clean up vomit in a classroom.
Clayfield eventually performed his janitorial duties as asked, but not before kicking over a bucket of water and refusing to hand his keys over to the supervisor, a ruckus that caused the principal to have the children removed from the room, the story noted.
Clayfield said: "I just lost it and something happened and it got blown out of proportion, I think. Twenty-two years I''ve worked there and to lose that over what I thought was a medical problem was devastating."
Clayfield apologized to his supervisor and stopped taking the drug that caused sleep deprivation, anxiety and agitation, the story added.
