Labour unions are formal organisations of workers who come together to collectively seek to improve their wages, working conditions, benefits, and job security through various strategies, including negotiation with employers (collective bargaining) and the use of tactics such as strikes when necessary. Unions provide a collective voice for workers, aiming to balance the power dynamic between individual employees and employers. They advocate for workers' rights, fair treatment, and safer workplaces. The history and influence of labour unions have played a significant role in shaping labor laws, workplace standards, and the overall distribution of economic power in many countries.
