“Section 7.  Employees shall have the right to self-organize to form, join, or assist labor organizations, to obtain collectively through representation of their own choosing, and to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or promotion…”


Employees have the legal right to help organize, to join and support a union of their own choosing.  This includes such activities as signing union card, getting others to sign cards, attending union meetings, wearing union buttons, passing out union literature and talking union to other employees.


Your protection under the National Labor Relations Board (NLRB).

It shall be an unfair labor practice for an employer to interfere with, restrain, or coerce employees in the exercise of their rights.


Employees are supposed to have a FREE CHOICE in deciding whether they want to use their right to organize.  Anything an employer does to interfere with this free choice is against the law.

For the past 85 years, members of Local 12 have been at the forefront of the Labor Movement, advocating for higher wages, safer working conditions, and advancing our craft.  Through our collective bargaining activities, the Operating Engineers have attained some of the most significantly improved working conditions in any workplace.

If you are working non-union, we invite you to join the movement of the Operating Engineers.  Solidarity moves mountains.
