Collective bargaining is a process of negotiation between employers and a group of employees aimed at agreements to regulate working salaries, working conditions, benefits, and other aspects of workers' compensation and rights for workers. The interests of the employees are commonly presented by representatives of a trade union to which the employees belong. A collective agreement reached by these negotiations functions as a labour contract between an employer and one or more unions, and typically establishes terms regarding wage scales, working hours, training, health and safety, overtime, grievance mechanisms, and rights to participate in workplace or company affairs. Such agreements can also include 'productivity bargaining' in which workers agree to changes to working practices in return for higher pay or greater job security.
The union may negotiate with a single employer (who is typically representing a company's shareholders) or may negotiate with a group of businesses, depending on the country, to reach an industry-wide agreement. Collective bargaining consists of the process of negotiation between representatives of a union and employers (generally represented by management, or, in some countries such as Austria, Sweden, Belgium, and the Netherlands, by an employers' organization) in respect of the terms and conditions of employment of employees, such as wages, hours of work, working conditions, grievance procedures, and about the rights and responsibilities of trade unions. The parties often refer to the result of the negotiation as a collective bargaining agreement (CBA) or as a collective employment agreement (CEA).
The term "collective bargaining" was first used in 1891 by Beatrice Webb, a founder of the field of industrial relations in Britain. It refers to the sort of collective negotiations and agreements that had existed since the rise of trade unions during the 18th century.
In the United States, the National Labor Relations Act of 1935 made it illegal for any employer to deny union rights to an employee. The issue of unionizing government employees in a public-sector trade union was much more controversial until the 1950s. In 1962, President John F. Kennedy issued an executive order granting federal employees the right to unionize.
An issue of jurisdiction surfaced in National Labor Relations Board v. Catholic Bishop of Chicago (1979) when the Supreme Court held that the National Labor Relations Board (NLRB) could not assert jurisdiction over a church-operated school because such jurisdiction would violate the First Amendment establishment of freedom of religion and the separation of church of state.
The right to collectively bargain is recognized in international human rights conventions. Article 23 of the Universal Declaration of Human Rights identifies the ability to organize trade unions as a fundamental human right. Article 2(a) of the International Labour Organization's Declaration on Fundamental Principles and Rights at Work defines the "freedom of association and the effective recognition of the right to collective bargaining" as an essential right of workers. The Freedom of Association and Protection of the Right to Organise Convention, 1948 (C087) and several other conventions specifically protect collective bargaining through the creation of international labour standards that discourage countries from violating workers' rights to associate and collectively bargain.
Union members and other workers covered by collective agreements get, on average, a wage markup over their nonunionized (or uncovered) counterparts. Such a markup is typically 5–10 percent in industrial countries.
Unions tend to equalize the income distribution, especially between skilled and unskilled workers.
The deadweight loss associated with unions is 0.2 to 0.5 percent of GDP, which is similar to monopolies in product markets.
An empirical model for empirical analysis and computer-assisted collective bargaining has been developed at the Hans Böckler Foundation.
Only one in three OECD employees have wages which were agreed on through collective bargaining. The Organization for Economic Co-operation and Development, with its 36 members, has become an outspoken proponent for collective bargaining as a way to ensure that the falling unemployment also leads to higher wages.
In June 2007 the Supreme Court of Canada extensively reviewed the rationale for regarding collective bargaining as a human right. In the case of Facilities Subsector Bargaining Association v. British Columbia, the Court made the following observations:
The right to bargain collectively with an employer enhances the human dignity, liberty and autonomy of workers by giving them the opportunity to influence the establishment of workplace rules and thereby gain some control over a major aspect of their lives, namely their work... Collective bargaining is not simply an instrument for pursuing external ends... rather [it] is intrinsically valuable as an experience in self-government... Collective bargaining permits workers to achieve a form of workplace democracy and to ensure the rule of law in the workplace. Workers gain a voice to influence the establishment of rules that control a major aspect of their lives.
In Sweden the coverage of collective agreements is very high despite the absence of legal mechanisms to extend agreements to whole industries. In 2018, 83% of all private-sector employees were covered by collective agreements, 100% of public sector employees and in all 90% (referring to the whole labor market). This reflects the dominance of self-regulation (regulation by the labour market parties themselves) over state regulation in Swedish industrial relations.
While labour movements in Australia had a history of being suppressed through anti-trade union legislation in the first century of colonisation, by the beginning of the 1900s, union and guild led campaigns and strikes had begun to secure better working conditions for labourers across Australia. In 1904, threats of non-union organised Wildcat strikes motivated parliament to adopt the Commonwealth Conciliation and Arbitration Act 1904. The Act outlined new laws governing how Industrial relation disputes could be negotiated by employers and employees, formalising a process for collective bargaining.
While smaller pieces of legislation would continue to change the landscape of collective bargaining across Australia throughout the 1900s, national pushback against the introduction of changes made to industrial relations laws in 2005 led to the adoption of the Fair Work Act 2009.
The 2009 Act outlines collective bargaining practice allowed by federal Australian law. Some of the conditions and processes outlined by the law include the use of enterprise bargaining agreements, overall roles for unions during normal work and bargaining periods, good faith bargaining requirements for both parties, and the use of bargaining agents.
In the United States, the National Labor Relations Act (1935) covers most collective agreements in the private sector. This act makes it illegal for employers to discriminate, spy on, harass, or terminate the employment of workers because of their union membership or to retaliate against them for engaging in organizing campaigns or other "concerted activities", to form company unions, or to refuse to engage in collective bargaining with the union that represents their employees. It is also illegal to require any employee to join a union as a condition of employment. Unions are also able to secure safe work conditions and equitable pay for their labor.
