The UA represents approximately 370,000 skilled tradespeople in North America and Australia. More than 50,000 of its members are Canadian. UA tradespeople include plumbers, pipe fitters, sprinkler fitters and service technicians. They install, remodel, or maintain systems that carry water, steam, air and other liquids or gases necessary for sanitation, industrial production, and heating and air conditioning.
In the late 1800s, plumbers, steamfitters and gas fitters were generally associated with independent local unions that catered to a variety of trades. In 1889, many of these unions began to focus solely on one kind of trade, inspiring the need for the UA. The UA’s first general president, P.J. Quinlan, is credited as first acknowledging the presence of the UA and setting the foundation for the union’s role in strike aid, building apprenticeships and worker treatment.
