About the United Association

The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States, Canada and Australia (UA), affiliated with the national building trades, represents approximately 370,000 plumbers, pipe fitters, sprinkler fitters and service technicians in North America and Australia. The "UA", as it is commonly known is a multi-craft union whose members are engaged in the fabrication, installation and servicing of piping systems.

The United Association has been training qualified pipe tradesmen longer than anyone else in the industry. The UA boasts the premier training programs available in the industry today, including five-year apprenticeship programs, extensive journeyman training organized instructor training, and certification programs.

Two Nations, One Union

The bonds of brotherhood recognize no political or geographic boundaries when it comes to United Association membership. Ours is truly an international organization with more than 50,000 UA brothers and sisters located in Canada. Working with the same pride and determination as their fellow members in the U.S., our Canadian brothers and sisters continue to demonstrate the high degree of quality craftmanship necessary to construct the homes, schools, office buildings, refineries, power plants and industrial facilities necessary to a strong and vibrant national economy. At the same time, our fellow members north of the border play an important role in helping to maintain and promote United Association solidarity as we join together to reap the benefits of unionism and pride in our united cause.

How Does The United Association Operate?

The United Association is led by a group of General Officers who are elected by the delegates at a convention held every five years. Members who attend these conventions as delegates are elected by their fellow members at the local union level.

The General Office has many departments and functions, including Jurisdiction, Organizing, Training, Legislative and Safety. Each General Officer pledges to uphold the United Association constitution and to protect the interest and welfare of all members.

How Many Locals and Members Are In The United Association?

Currently there are over 300 local unions in the United Association, in excess of 370,000 members.

The local unions are located in all of the 50 states of America and every province of Canada. Members are free to travel from one local area to another to satisfy the needs of local work conditions.

Founded in 1889, the United Association is one of the most respected and influential building trades unions in the U.S. and Canada today. It serves as a collective voice for workers through negotiation and collective bargaining with employing contractor groups, such as the Mechanical Contractors Association of America, and the National Association of Plumbing-Heating-Cooling Contractors. The UA is also a key member of the Building and Construction Trades Department, the AFL-CIO, and the Canadian Federation of Labour.
