You have the legal right under Section 7 (U.S. Code Title 29, Chapter 7, § 157) of the National Labor Relations Act to join or support a union and to:

• Attend meetings to discuss joining a union.
• Read, distribute, and discuss union literature (as long as you do this in non-work area during non-work times, such as during breaks or lunch hours.)
• Wear union buttons, T-shirts, stickers, hats, or other items on the job (providing you can wear non-union related items.  The company cannot discriminate because it relates to union.)

It is illegal under Section 8(a) (U.S. Code Title 29, Chapter 7, § 158a) and constitutes unfair labor practices for the employer to do the following:

• Threaten to or actually fire, lay off, discipline, harass, transfer, or reassign employees because they support the union.
• Favor employees who don't support the union over those who do in promotions, job assignments, wages, hours, enforcement of rules, or any other working condition.
• Shut down the work site or take away any benefits or privileges employees already enjoy in order to discourage union activity.
• Promise employees a pay increase, promotion, benefits, or special favors if they oppose the union.
• Spy on union activities.
