History of UA Local 100

The Beginning:
Plumbers and Steamfitters Local Union No. 100 was issued its charter, dated December 1, 1892, by the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada.


For many years throughout history, attempts were made to form organizations of workers. These attempts met with different reactions from employees, government, the business community and the general public. The United Association of Plumbers and Pipefitters was officially born on October 11, 1889, when forty delegates from twenty-three Local Unions traveled to Washington, D.C. to attend the founding convention. Plumbers and Pipefitters organizations from cities across the nation applied for charters in this new organization. It was three years after the International Union was formed that Local Union No. 100 received their charter.

There are five hundred plus affiliated local unions today. It is an honor to be one of the Local Unions that has reached its one hundredth anniversary.

The formation of Local No. 100 was no easy task, since many viewed unions as illegal, and fought the formation of unions. Even as late as the early nineteen hundreds, union members were arrested for only attempting to have a meeting. Meetings were very private, a password was established for entrance to the meetings and a password is still in use today.

The main concern of the representative for Local No. 100 was to form a standard wage scale, the improvement of working condition and a general improvement of the workers' standard of living.

The members wanted a say and to have influence in the things that affected their everyday lives.

History has shown that these goals can be accomplished when workers band together in an organized effort.

Plumbers & Steamfitters Local No. 100 has not only tried to improve the lives of its members, but the lives of all working people.

From the beginning, Local No. 100 realized that for an even greater influence, it would be to their benefit to form an organization comprised of the various unions. This brought about the formation of what is our present day AFL-CIO and Building Trades.

The members of Local No. 100, as well as other Building Trades Unions in Dallas have played a part in the construction of nearly every major landmark building in Dallas. This has not always been something that was just given to us, but something that we have struggled for.

At times in our history, members have not always performed 100% of the plumbing, heating and air conditioning work on these buildings, but you will find evidence of their work somewhere from the basement floor drains to the mechanical equipment rooms and roof drains.

As we move into the future, we in Local No. 100 welcome the challenges and demands that will be placed on us. We have survived many threats to our existence over the past 100 years, through wars, economic depression, and most recently, an anti-union government.

Our programs have survived all these threats and that testifies to their integrity and soundness.

In the next decade, we will continue to evaluate and adapt ourselves and our programs as the needs of our industry dictates.
