The National Labor Relations Act (NLRA) forbids employers from interfering with, restraining, or coercing employees in the exercise of their rights to organize, form, join or assist a labor organization for collective-bargaining purposes . . .
Employers violate the law by:
• Threatening employees with loss of jobs or benefits if they join or vote for a union.
• Questioning employees about their union activities or membership in such circumstances as will tend to restrain or coerce the employees.
