Final answer:
The statement that management-exclusive job evaluation is disfavored by union leaders because it limits bargaining opportunities and freezes wage structure is true, as it diminishes the union's role in negotiating wages and conditions.
Step-by-step explanation:
Union leaders often view management-exclusive job evaluation with disfavor because it indeed tends to limit bargaining opportunities and freeze wage structure. This statement is true. In labor relations, bargaining opportunities are important for unions to negotiate better wages and working conditions for their members. When management alone evaluates jobs, sets wage scales, and determines increases without union involvement, it diminishes the union's role and can lead to a rigid wage structure that does not adequately reflect the workers' contributions or market conditions. Unions typically serve to protect workers' interests and seek to prevent management from imposing constraints that would undermine the workers' abilities to negotiate effectively.
