Final answer:
The statement that unions file several grievances to support and document their demands during labor negotiations is true. These grievances become vital in collective bargaining, helping to negotiate better terms for the labor contract. The correct answer is option a.
Step-by-step explanation:
A common union tactic is to file several grievances over a particular issue to buttress and document union demands during negotiation of the subsequent labor agreement. This statement is true. Unions use this strategy to strengthen their position and show a pattern of issues that require resolution. This collective action can eventually lead to collective bargaining, where labor unions negotiate with employers to create a labor contract that addresses the concerns raised by the workers.
Negotiating a labor contract can involve discussions on wages, work rules, complaint procedures, promotions, benefits, workplace safety, and policies. The filing of grievances is a part of the complaint procedures that signals to the employer the areas that need improvement, and these grievances become a crucial part of the discussion during contract negotiations.
