Labour Day

When I asked a colleague what we celebrate on Labour Day, the answer was: "We celebrate that we have a day off". Not quite. Some people believe that labour day originates in Canada. On September 5, 1882 the Knights of Labour held their first parade in New York, but the idea originates in Canada, with marches held in Toronto and Ottawa in support of 24 leaders of the Toronto Typographical Union, who were imprisoned because membership of a union was an offense against the criminal conspiracy in restraint of trade law.
