Final answer:
Silent Objection was not a strategy used by labor unions. Instead, they employed collective bargaining, strikes, and boycotts to achieve their goals.
Step-by-step explanation:
Labor Union Tactics
Which of the following was NOT one of the tactics that labor unions used to achieve their goals? The answer is Silent Objection. Labor unions have a storied history of utilizing various strategies to advocate for the rights and interests of workers. Among the tactics they employed are collective bargaining and strikes. Collective bargaining is a negotiation process where the union and employer work together to agree upon employment terms. Strikes involve workers refusing to work until their demands are met. Boycotts were also used to apply pressure on employers and gain public support. However, Silent Objection was not a tactic used by labor unions to further their goals.
Labor unions like the Congress of Industrial Organizations (CIO) and the United Auto Workers (UAW) have historically taken aggressive actions to assert their demands, such as sit-down strikes, which were effective in compelling companies like General Motors to negotiate. Over time, labor unions have navigated a challenging landscape, facing opposition from business owners and public sentiment, particularly during times when unionization was associated with radical ideologies. Despite setbacks and the stigma of socialism, unions have continued to fight for better pay, working conditions, and benefits for workers.
