Unions are organizations formed by workers to protect their rights and improve their working conditions. They negotiate with employers on behalf of their members for better wages, benefits, and job security. By coming together, workers can have a stronger voice and influence in the workplace, making it easier to address issues like unfair treatment or unsafe conditions. In many countries, unions play a crucial role in advocating for labor laws and policies that benefit all workers. They often organize strikes or protests to draw attention to their causes. Famous unions, like the United Auto Workers or the American Federation of Teachers, have made significant impacts on labor rights throughout history.
