Step-by-step explanation:
An organized group of employees that negotiates with employers about issues such as wages and working conditions is known as a (d) labor union. A labor union represents its members in discussions and negotiations with management, aiming to improve their employment conditions. This process is often referred to as collective bargaining, which can lead to the establishment of new work contracts that set out wage rates, working hours, health and safety conditions, and other benefits.
Labor unions can also influence broader industry and societal issues by engaging in activism that supports worker-friendly legislation or by challenging practices they see as unfair or detrimental to the workforce. Historically, labor unions have been instrumental in advocating for higher pay and safer working conditions, and they continue to play a key role in protecting workers' rights in many industries today.
