Trade unions are organizations formed by workers to protect their rights and interests in the workplace. They negotiate with employers on behalf of their members to secure better wages, benefits, and working conditions. By coming together, workers can have a stronger voice in discussions about their jobs. Trade unions also provide support and resources for their members, such as legal assistance and training programs. They play a crucial role in advocating for labor laws and policies that benefit all workers, contributing to a fairer and more equitable work environment.
