A trade union is an organized group of workers aiming to protect and advance the interests of its members through negotiations with employers for better pay and working conditions. The trade union movement in India has evolved over time, starting from the first union in 1877 to the establishment of various prominent unions with distinct objectives, reflecting the historical context of labor rights and industrialization. Trade unions play a crucial role in advocating for workers' rights, fostering solidarity, and contributing to social and economic welfare.
