what are the main objectives of labor unions
Trade union A trade union or trades union, also called a labour union (Canada) or labor union (US), is an organization of workers who have come together to achieve many common goals; such as protecting the integrity of its trade, improving safety standards, and attaining better wages, benefits (such as vacation, health care, and retirement), and working conditions through the increased bargaining power wielded by the creation of a monopoly of the workers.[1] The trade union, through its leadership, bargains with the employer on behalf of union members (rank and file members) and negotiates labour contracts (collective bargaining) with employers. The most common purpose of these associations or unions is "maintaining or improving the conditions of their employment".[2] This may include the negotiation of wages, work rules, complaint procedures, rules governing hiring, firing and promotion of workers, benefits, workplace safety and policies.
