It is your right as an American worker to form a union.  The 1935 National Labor Relations Act (NLRA) is the federal law that guarantees you this right.  The NLRA was passed during a time when workers had little protection in the workplace. They could be fired without cause, had few safety precautions in place, had limited access to decent health care, and probably had no retirement to look forward to. 

Following the passage of the NLRA, tens of millions of Americans chose to form labor unions at their workplaces.  By 1955, approximately 35% of all workers in the United States were union members.  These workers fought for and won improvements in almost every aspect of our workplaces.  Thanks to these workers and their unions, the decades that followed saw the creation of the American middle class.   

Sadly, for an ever increasing number of American workers, the poor conditions mentioned above are common again.  Luckily, the NLRA is still the law of the land.  You still have the right to form a union of your choosing.  You still have the right to organize together and bargain over wages and working conditions.  The International Union of Operating Engineers, Local 564 is committed to assisting you in exercising these rights. 

Your Right to a Union 

35 Things your Employer May Not Do! 

The rights mentioned to the left are not the only protections American workers have when they decide to form a union. For instance, did you know that your employer may not ask employees how they intend to vote in a union election?  Or that your employer may not announce that they will "not deal with the union"?  Did you realize that your employer is not allowed to make distinctions between union and non-union employees when assigning desirable work or overtime?  

These are just a few of the "35 Things Your Employer May Not Do".
