How do I find my staff representative?
You should start by contacting your local union office for help. If you don’t know your local information or still need information, please contact your district office. You can find your district office here.
What is a local union and how do I find mine?
The USW represents members across the United States, Canada and the Caribbean. The union is broken into 12 districts, each with a director, who helps provide guidance and resources for members in a set geographic area. Local unions, or locals, serve as the smallest branch, operating in close proximity to an individual, typically within the same community. Some are comprised of a single workplace or contract, while others, called amalgamates, bring together workers from several employers. Locals are designated by numbers, for example, USW Local 1234. Members elect their local leadership from within their ranks, and these elected officers serve as the primary contacts if members have questions or concerns. If you do not know how to get in touch with your local union, call your district office and they can help you.
Do I have a pension and how do I find a loved ones?
Please call the USW Pension and Benefits Department at 412-562-1673 during regular working hours and our staff should be able to help you find the information you need.
How do I start a union at work?
There are a few ways you can become a USW member. First, you can form a union at your workplace, a process called organizing. If you would like more information, please contact our Organizing Department at 877-511-8792, or by filling out the online form on this page and someone will get in touch with you at your convenience.
The second way you can become a USW member is to get hired at facility where the workers are already represented by the USW. The USW is not a hiring hall or apprenticeship program so we cannot directly help you find employment. However, if you call the district office closest to you may be able to get information about employment opportunities at USW facilities.
You also can join our Associate Member Program online for free. This program is open to anyone who wants to be a part of the USW but does not have the ability for USW representation at your workplace.
