Employees have the right to unionize, to join together to advance their interests as employees, and to refrain from such activity. It is unlawful for an employer to interfere with, restrain, or coerce employees in the exercise of their rights. For example, employers may not respond to a union organizing drive by threatening, interrogating, or spying on pro-union employees, or by promising benefits if they forget about the union.

Section 7 of the National Labor Relations Act (the Act) guarantees employees "the right to self-organization, to form, join, or assist labor organizations, to bargain collectively through representatives of their own choosing, and to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or protection," as well as the right "to refrain from any or all such activities."

Section 8(a)(1) of the Act makes it an unfair labor practice for an employer "to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in Section 7" of the Act.
