Ask other employees to support the union, to sign union cards or petitions, or to file grievances. In most situations, the employees prove majority support through a secret-ballot election conducted by the National Labor Relations Board. Under Section 8 of the National Labor Relations Act, your employer cannot legally punish or discriminate against any worker because of union activity. 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. Promise employees a pay increase, promotion, benefit, or special favor if they oppose the union.
Some employers try to prevent the workers from joining a union.
The best way to encourage your employers to recognize your union and negotiate a fair contract is to build a strong organization where you work. The Labor Board has the power to order an employer to stop interfering with employee rights, to provide back pay, and to reverse any action taken against workers for union activity. Immediately reporting any such incidents to your organizing committee and the union staff. 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. I'm among the first to say I believe in unions.
