Wear union buttons, T-shirts, stickers, hats, or other items on the job. Sign a petition or card asking your employer to recognize and bargain with the union. Sign petitions or file grievances related to wages, hours, working conditions, and other job issues. Ask other employees to support the union, to sign union petitions or cards, or to file grievances. Under Section 8 of the National Labor Relations Act, your employer cannot legally punish or discriminate against any worker because of union activity.
Some employers try to prevent the workers from joining a union.
The best way to encourage your employer to recognize your union and negotiate a fair contract is to build a strong organization where you work. Keep written notes of any incidents in which company officials or supervisors threaten, harass, or punish workers because of union activity. Your notes don t have to be worded a certain way, but you should include what was said or done, who was involved, where and when it happened, and the names of any witnesses. A' cards, as they are referred to in the Union, are used as proof of majority support. Joining the Union is a separate and distinctly different action.
