Correct Response: A. According to The National Labor Relations Act, employers are forbidden from interfering with employees in the exercise of rights relating to organizing for collective bargaining purposes. Therefore, a company that disciplines an employee for advocating for the formation of a union on company grounds during the employee's lunch hour would be violating federal law. Employers have the right to bar employees from coming to work during a labor dispute, but the company may only hire temporary workers to take their place (B). Barring nonemployee union organizers who distribute pro-union leaflets in the company parking lot (C) is legal and not a violation of federal labor law. The company has the legal right to hire permanent replacement workers (D) after collective bargaining breaks down and union members go on strike.
