Employers often try to persuade employees not to unionize because a union is often much stronger than an individual employee. An employer is required to bargain in good faith with a union. Under the National Labor Relations Act (NLRA), an employer may not restrain an employee in the right to organize, form, help, or join a labor organization, such as a union, for collective bargaining reasons.Your employer can try to persuade your coworkers and you not to form a union, but not by threatening violence, lying, or using other coercive actions. For example, an employer cannot threaten employees with unemployment if they join a union. However, your labor organization also may not restrain or coerce employees by threatening them with job loss for failing to support the union.The NLRA also prevents employers from restraining employees in their efforts to improve employment conditions. For example, your employer cannot ask about your union activities such that you cannot exercise your right to discuss working conditions.
