Explanation: During a lawful economic strike, employers do have the right to hire employees to replace the striking employees. Answer choices A, C, D, and E are incorrect because they each represent types of unfair labor practices. Employers may not fire employees who refuse to cease striking instead of returning to work. They also may not encourage the union to disband and/or suggest the formation of a new union. Nor may the employer disband union bargaining and require new representation, or restrict union bargaining if this negatively impacts company's finances.
