When labor issues arise, the leadership of Local 351 utilizes the expert attorneys in the field of labor and employment law at the firm of Williams Hart in Houston, Texas.

The role of Union Stewards at each facility are vital in cultivating a productive and respectful relationship between the Union members and their respective employers. Local 351 provides continuing training and education to the Union Stewards to insure each Union Steward understands the role of a Union Steward versus just being an employee of his/her employer.

In addition to representing the current Union membership of Local 351, we are constantly promoting the labor movement by growing the membership of Local 351 by organizing new groups within our jurisdiction.
