Why does collective bargaining have the same general effect on unemployment as a minimum wage?

Collective bargaining and minimum wage laws both set a floor for wages, which can lead to increased labor costs for employers. As a result, some businesses may reduce hiring or lay off workers to manage these higher expenses, potentially leading to higher unemployment rates. Additionally, just as a minimum wage can limit employment opportunities for low-skilled workers, collective bargaining agreements can create similar barriers by establishing higher wage standards that may not align with market demand. Both mechanisms can thus have a comparable impact on overall employment levels.
