Final answer:
Double-breasting is a true practice used in union-avoidance strategies, where a company operates both a unionized and a non-unionized business to avoid union rules and costs, albeit controversially.
Step-by-step explanation:
Double-breasting is indeed a practice employed by a company with a "union-avoidance" strategy. This is true. To clarify, when a company engages in double-breasting, it operates two separate lines of business—one unionized and one non-unionized. The non-unionized entity is often established to perform the same type of work as the unionized entity but without the union involvement. This practice allows the parent company to offer services at a lower cost by avoiding union wage scales, benefiting from more flexible work rules, and sidestepping collective bargaining agreements. However, it is a controversial practice and can lead to legal and ethical challenges.
