The Utility Workers Union of America (UWUA) is a labor union associated with the AFL-CIO representing less than 42,000 workers in electric, gas, steam, water, and nuclear industries.
UWUA is the exclusive voice for its members. Union members give up their voice to the UWUA. Their constitution makes that really clear.
In addition, each local union has its own bylaws that lay out things like dues, fees, fines, special assessments, disciplinary procedures and loyalty pledges you’d be expected to take to make sure you stay in line.
