Why Choose a Union?

We get it done right the first time. When you choose to have your job done by the UA, you choose to work with the best in the piping industry. Today’s Mechanical contractor must to be multi faceted in their approach to working with their clients. The UA recognizes this and has built our organization to support the contract across a wide range of jobs in all sectors, Industrial, Commercial, Institutional and Residential.

In the past, Union work was relegated to large scale projects. This type of exclusionary thinking does not work in today’s economic landscape. We continue to work with our contractors to deliver into markets that were traditionally the work of the non-union contractors by continuing to deliver the quality the UA is known for combined with the flexibility the contractors need.

We recognized, and responded to our Contractors concerns regarding the widening gap in wages for Union vs. Non-union skilled trades. As a result, we developed a Market Recovery Fund for Stabilization. This Fund provides financial assistance to our Contractors during the tender process allowing a more competitive advantage.

The United Association can work with you in all stages of your successful project, from tender to substantial completion, and beyond, with practical maintenance and service Agreements that can be tailored to your circumstance.

Although it is true that only about 20 percent of American workers are in unions, that 20 percent sets the standards across the board in salaries, benefits and working conditions. If you are making a decent salary in a non-union company, you owe that to the unions. One thing that corporations do not do is give out money out of the goodness of their hearts.
