United Association of Plumbers and Steamfitters Local 159 The local unions are located in all of the 50 states of America and every province of Canada.

Local 159 was founded on April 3rd, 1915 in Martinez, California. 90 years later, our offices are still headquartered in Martinez where we have our union hiring hall, Journeymen and Apprentice Training facility and assembly hall. With over 650 members and over 100 union contractors, we provide skilled plumbers, steamfitters, HVAC Refrigeration technicians and service plumbers for work in Contra Costa County and beyond. Currently there are over 300 local unions in the United Association, with in excess of 340,000 members. 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.

Brothers and Sisters this is just a friendly reminder to get your RSVP's in for the Children's Christmas Party by this Friday November 6th. We want to make sure to communicate with Santa how many gifts he will need before he leaves the North Pole!

Four of our sisters attended NABTU's 2026 Tradeswomen Build Nations Conference in Houston, Texas this last weekend. This was our first time attending in quite some time and the event has grown astronomically since it first started. As always, the UA led the way by having the biggest delegation of woman with 1200 strong in attendance. Total attendance from all crafts was around 5000. Leading by example is what we do, opening up doors and not placing barriers to allow the success for all to succeed in our industry is a win for all. We'd like to thank our sisters for attending and representing UA Local 159 proudly.

Brothers and Sisters,

This November, our future is on the ballot.

One-party control of Washington has failed. Prices at the pump keep on rising, inflation is out of control, and life just does not feel affordable anymore. President Trump was elected to lower costs and end foreign wars. He broke that promise.

As he continues to fight a war that nobody wants, families across the country struggle to make ends meet. It is time for us to get in the game, fight for a better future, and get real: let’s bring some common-sense checks and balances back to government.

That’s why the UA is launching our largest and most ambitious nationwide member-to-member digital ad campaign this midterm season. We did the research and put together a team of Democrat, Republican, and Independent candidates who will always fight for our jobs, make things more affordable for UA families, and end forever wars.

Take a look for yourself at uagetinvolved.org/ua-team and share with your UA Brothers and Sisters before you make a plan to vote this November.

Fraternally,

Mark McManus

When it comes to the UA, there’s only one team: ours. When our jobs, wages, pensions, and union way of life are on the line, we stick together.

This November Prop 45 will be put into the voter's hands and if this proposition gets through we as a labor union could face an even greater threat to our market share of construction projects. Prop 45 is designed to gut the California Environmental Quality Act better known as "CEQA". When a developer comes to our communities, they have one thing in mind and that's PROFIT. When labor engages in the CEQA process it's about making sure that the project is the right project for the communities that our members live in. Prop 45 if passed will take not just labor's voice out of the room but also yours as a community member. Prop 45 is using California's affordability crisis to convince voters as to why this is a good thing when in actuality it's developers choosing profit over people and getting rid of the CEQA process that ensures proposed projects are the right projects for the community they are being built in. We encourage you to vote "NO ON PROP 45" this November to ensure we continue to have a voice in how our communities are shaped and built in the future.

When we roll together, we can do great things and a fine example of that was the recent Bocce Ball Tournament for the Central Labor Councils Hardship Fund. It was a day of great brotherly and sisterly camaraderie, great bbq, and a fun game of Bocce Ball. Big thanks to all of our 159 apprentices that volunteered their time to serve food for the event and an even bigger thank you to our Apprenticeship Coordinator Brian Lescure that manned the bbq. I am happy to say that 1 of our Local 159 teams finished 2nd place and the other losing a close 3rd place match to finish 4th. Thank you Contra Costa Central Labor Council for putting on such a great event that brought a lot of brothers and sisters together in one place!
