Equal pay for equal work
Equal pay for equal work is the concept of labor rights that individuals doing the same work should receive the same remuneration. It is most commonly used in the context of sexual discrimination, in relation to the gender pay gap. Equal pay relates to the full range of payments and benefits, including basic pay, non-salary payments, bonuses and allowances. Some countries have moved faster than others in addressing the problem. Since President Kennedy signed the Equal Pay Act in 1963, it has been illegal in the United States to pay men and women working in the same place different salaries for similar work.

As wage-labor became increasingly formalized during the Industrial Revolution, women were often paid less than their male counterparts for the same labor, whether for the explicit reason that they were women or under another pretext. The principle of equal pay for equal work arose at the same time, as part of first-wave feminism, with early efforts for equal pay being associated with nineteenth-century Trade Union activism in industrialised countries: for example, a series of strikes by unionised women in the UK in the 1830s. Pressure from Trade Unions has had varied effects, with trade unions' own patriarchal character sometimes promoting conservatism. However, following the Second World War, trade unions and the legislatures of industrialized countries gradually embraced the principle of equal pay for equal work; one example of this process is the UK's introduction of the Equal Pay Act 1970 in response both to the Treaty of Rome and the Ford sewing machinists strike of 1968. In recent years European trade unions have generally exerted pressure on states and employers for progress in this direction.
International human rights law
In international human rights law, the statement on equal pay is the 1951 Equal Remuneration Convention, Convention 100 of the International Labour Organisation, a United Nations body. The Convention states that
- Each Member shall, by means appropriate to the methods in operation for determining rates of remuneration, promote and, in so far as is consistent with such methods, ensure the application to all workers of the principle of equal remuneration for men and women workers for work of equal value.
Equal pay for equal work is also covered by Article 7 of the International Covenant on Economic, Social and Cultural Rights, Article 4 of the European Social Charter, and Article 15 of African Charter on Human and Peoples' Rights. The Constitution of the International Labour Organization also proclaims "the principles of equal remuneration for equal value".
The EEOC's four affirmative defenses allows unequal pay for equal work when the wages are set "pursuant to (i) a seniority system; (ii) a merit system; (iii) a system which measures earnings by quantity or quality of production; or (iv) ... any other factor other than sex." A pay differential due to one of these factors is not in breach of the Convention.
Legal situation by jurisdiction
European Union/European Economic Area
Post-war Europe has seen a fairly consistent pattern in women's participation in the labour market and legislation to promote equal pay for equal work across eastern and western countries.
Some countries now in the EU, including France, Germany, and Poland, had already enshrined the principle of equal pay for equal work in their constitutions before the foundation of the EU (see table below). When the European Economic Community, later the European Union (EU), was founded in 1957, the principle of equal pay for equal work was named as a key principle. Article 141 of the Treaty of Rome says 'each Member State shall ensure that the principle of equal pay for male and female workers for equal work or work of equal value is applied.' While socially progressive, this decision does not necessarily indicate widespread progressive attitudes among the signatories to the treaty:
- While this is often viewed as an example of the progressive nature of the European community, some argue that Article 141 (previously 119) was included largely as a concession to the French who already had equal pay legislation and feared that they would be at a comparative disadvantage.
The EEC's legislation was clarified in 1975 by the binding and directly applicable equal pay directive 75/117/EEC. This prohibited all discrimination on the grounds of sex in relation to pay; this and other directives were integrated into a single Directive in 2006 (2006/54/EC).
At the national level the principle of equal pay is in general fully reflected in the legislation of the 28 EU member states and the additional countries of the European Economic Area (EEA), Iceland, Liechtenstein and Norway. The EU candidate countries of Macedonia and Turkey also adapted their legislation to EU standards. The main national legislation concerning pay equity between men and women for different European countries is as follows.

Federal law: Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964
The first attempt at equal pay legislation in the United States, H.R. 5056, "Prohibiting Discrimination in Pay on Account of Sex," was introduced by Congesswoman Winifred C. Stanley of Buffalo, N.Y. on June 19, 1944. Twenty years later, Legislation passed by the Federal Government of the United States in 1963 made it illegal to pay men and women different wage rates for equal work on jobs that require equal skill, effort, and responsibility and are performed under similar working conditions. One year after passing the Equal Pay Act, Congress passed the 1964 Civil Rights Act. Title VII of this act makes it unlawful to discriminate based on a person’s race, religion, color, or sex. Title VII attacks sex discrimination more broadly than the Equal Pay Act extending not only to wages but to compensation, terms, conditions or privileges of employment. Thus with the Equal Pay Act and Title VII, an employer cannot deny women equal pay for equal work; deny women transfers, promotions, or wage increases; manipulate job evaluations to relegate women’s pay; or intentionally segregate men and women into jobs according to their gender.
Since Congress was debating this bill at the same time that the Equal Pay Act was coming into effect, there was concern over how these two laws would interact, which led to the passage of Senator Bennett’s Amendment. This Amendment states: “It Shall not be unlawful employment practice under this subchapter for any employer to differentiate upon the basis of sex . . . if such differentiation is authorized by the provisions of the [Equal Pay Act].” There was confusion on the interpretation of this Amendment, which was left to the courts to resolve. Thus US federal law now states that "employers may not pay unequal wages to men and women who perform jobs that require substantially equal skill, effort and responsibility, and that are performed under similar working conditions within the same establishment."
In Washington, Governor Evans implemented a pay equity study in 1973 and then another in 1977. The results clearly showed that when comparing male and female dominated jobs there was almost no overlap between the averages for similar jobs and in every sector, a twenty percent gap emerged. For example, a food service worker earned $472 per month, and a Delivery Truck Driver earned $792, though they were both given the same amount of “points” on the scale of comparable worth to the state. Unfortunately for the state, and for the female state workers, his successor Governor Dixie Lee Ray failed to implement the recommendations of the study (which clearly stated women made 20 percent less than men). Thus in 1981, AFSCME filed a sex discrimination complaint with the EEOC against the State of Washington. The District Court ruled that since the state had done a study of sex discrimination in the state, found that there was severe disparities in wages, and had not done anything to ameliorate these disparities, this constituted discrimination under Title VII that was “pervasive and intentional.” The Court then ordered the State to pay its over 15,500 women back pay from 1979 based on a 1983 study of comparable worth. This amounted to over $800 million. However, the United States Court of Appeals for the Ninth Circuit overturned this decision, stating that Washington had always required their employees’ salaries to reflect the free market, and discrimination was one cause of many for wage disparities. The court stated, “the State did not create the market disparity . . . [and] neither law nor logic deems the free market system a suspect enterprise.” While the suit was ultimately unsuccessful, it led to state legislation bolstering state workers’ pay. The costs for implementing this equal pay policy was 2.6% of personnel costs for the state.
In Minnesota, the state began considering a formal comparable worth policy in the late 1970s when the Minnesota Task Force of the Council on the Economic Status of Women commissioned Hay Associates to conduct a study. The results were staggering and similar to the results in Washington (there was a 20% gap between state male and female workers pay). Hay Associates proved that in the 19 years since the Equal Pay Act was passed, wage discrimination persisted and had even increased over from 1976 to 1981. Using their point system, they noted that while delivery van drivers and clerk typists were both scaled with 117 points each of “worth” to the state, the delivery van driver (a male dominated profession) was paid $1,382 a month while the clerk typist (a female dominated profession) was paid $1,115 a month. The study also noted that women were severely underrepresented in manager and professional positions; and that state jobs were often segregated by sex. The study finally recommended that the state take several courses of action: 1) establish comparable worth considerations for female- dominated jobs; 2) set aside money to ameliorate the pay inequity; 3) encourage affirmative action for women and other minorities and 4) continue analyzing the situation to improve it. The Minnesota Legislature moved immediately in response. In 1983 the state appropriated 21.8 million dollars to begin amending the pay disparities for state employees. From 1982 to 1993, women’s wages in the state increased 10%. According to the Star Tribune, in 2005 women in Minnesota state government made 97 cents to the dollar, ranking Minnesota as one of the most equal for female state workers in the country.
Under Australia's old centralised wage fixing system, "equal pay for work of equal value" by women was introduced in 1969. Anti-discrimination on the basis of sex was legislated in 1984.
Figures released by the Australian Workplace Gender Equality Agency, an Australian national government agency, show that a woman’s wages, on average, reached a record figure gap of 18.8% less than a man’s in November 2014. This is despite a law being passed in 1984 by the Australian legislature making sexual discrimination in the workplace illegal. In November 2011, Australian Prime Minister Julia Gillard announced efforts by the national government to improve salaries of the 150,000 lowest-paid workers in Australia, roughly 120,000 women, by contributing A$2 billion over the next 6 years.
The figures change substantially when other factors are taken into account. Geographically, female workers living in the Australian Capital Territory show the lowest wage gap in the country at 11.7%. The highest wage gap is 25.7% in Western Australia.
A survey by industry shows that the lowest wage gap is in the area of Public Administration and Safety, with a wage gap of 7.2%. The highest wage gap is in the financial and insurance services industry, with a wage gap of 29.6%. The continuation of the wage gap in Australia is influenced by persistent discriminatory societal factors as to what a woman should or should not be allowed to do in the workplace. Australian society also relies heavily on women to take on the unpaid caring roles, further hindering their access to the working marketplace.
As of November 2014, the wage gap in the private sector stands at 22.4%, while in the public sector it is 12.3%. This is primarily due to the method at which salaries are negotiated. In the private sector, wages are decided by individual negotiation, whereas in the public sector, wages are usually arrived at through collective bargaining agreements.
In Canadian usage, the terms pay equity and pay equality are used somewhat differently from in other countries. The two terms refer to distinctly separate legal concepts.
Pay equality, or equal pay for equal work, refers to the requirement that men and women be paid the same if performing the same job in the same organization. For example, a female electrician must be paid the same as a male electrician in the same organization. Reasonable differences are permitted if due to seniority or merit.
Pay equality is required by law in each of Canada’s 14 legislative jurisdictions (ten provinces, three territories, and the federal government). Note that federal legislation applies only to those employers in certain federally regulated industries such as banks, broadcasters, and airlines, to name a few. For most employers, the relevant legislation is that of the respective province or territory.
For federally regulated employers, pay equality is guaranteed under the Canadian Human Rights Act. In Ontario, pay equality is required under the Ontario Employment Standards Act. Every Canadian jurisdiction has similar legislation, although the name of the law will vary.
In contrast, pay equity, in the Canadian context, means that male-dominated occupations and female-dominated occupations of comparable value must be paid the same if within the same employer. The Canadian term pay equity is referred to as “comparable worth” in the US. For example, if an organization’s nurses and electricians are deemed to have jobs of equal importance, they must be paid the same. One way of distinguishing the concepts is to note that pay equality addresses the rights of women employees as individuals, whereas pay equity addresses the rights of female-dominated occupations as groups.
Certain Canadian jurisdictions have pay equity legislation while others do not, hence the necessity of distinguishing between pay equity and pay equality in Canadian usage. For example, in Ontario, pay equality is guaranteed through the Ontario Employment Standards Act while pay equity is guaranteed through the Ontario Pay Equity Act. On the other hand, the three westernmost provinces (British Columbia, Alberta, and Saskatchewan) have pay equality legislation but no pay equity legislation. Some provinces (for example, Manitoba) have legislation that requires pay equity for public sector employers but not for private sector employers; meanwhile, pay equality legislation applies to everyone.
In Taiwan, it legislate the Act of Gender Equality in Employment in 2002. It regulates that a boss must give the same salary to the workers who do the same work.The law prescribes that employers shall not discriminate against employees because of their gender or sexual orientation in the case of paying wages. Employees shall receive equal pay for equal work or equal value. However, if such differentials are the result of seniority systems, award and discipline systems, merit systems or other justifiable reasons of non-sexual or non-sexual-orientation factors, the above-mentioned restriction shall not apply.Employers may not adopt methods of reducing the wages of other employees in order to evade the stipulation of the preceding paragraph.
The news of unequal pay for equal work
According to a report released by the American Association of University Women (AAUW), the gender pay gap—which had significantly narrowed since the 1970s—has slowly plateaued in recent years. Compiling data from the Census Bureau, the Department of Education and the Bureau of Labor Statistics, AAUW calculated the median salaries for full-time employment in all 50 states and the District of Columbia. In the U.S., the average woman is paid 23 percent less than the average man. Although down from a 2012 figure of 91 percent, Washington, D.C. maintains the smallest wage gap in the U.S., with the median woman earning 90 percent of the median man ($60,116 vs. $66,754). Also consistent with last year's results, Wyoming came in last with women taking home 64 percent of men's average earnings ($33,152 vs. $51,932). While it remains important to note that geography and local industry have a large influence on differing salaries, there are other major factors that come into play—namely education level, race/ethnicity and age. AAUW analyzed the pay gap by looking at full-time, year-round workers over the age of 15. Beyond comparing salaries of all men to salaries of all women, the report broke down wage imbalances between the sexes along three additional demographics: race/ethnicity, education level and age. Race/Ethnicity Asian-American women had the largest gender wage gap while Hispanic or Latina women's earnings were most comparable to their male counterparts. Education While greater education does increase women's overall earnings, it does not significantly close the gender wage gap. At every academic achievement level, women's median salaries are less than men's by at least 21 percent. The pay gap is significantly linked to factors such as college major and type of job pursued after graduation, although there is still a large part that cannot be explained by career choice. In a 2012 analysis, AAUW found that even after controlling for occupation, industry, hours, work experience, college major, religion, race/ethnicity, GPA, education, number of children and marital status, women are paid only 82 percent of what their male peers are earning just a year after college graduation. Ten years out of college, the gap widens with women earning a mere 69 percent of what men earn.
The Nan Ya PCB corporation's female employee accused that the female employees' salary were less than male's. Besides,the company have sex discrimination on promotion and allowance obviously. And it had already against the Act of Gender Equality. The employee said that the company existed sex discrimination for long time and it made females' right damage. The trade union bargained with the employer for many years. In order to resolve the dispute, the employer add one thousand allowance to female employees per month. But the employees found it still can't eliminate the gender pay gap.
Criticism of equal pay for equal work
Criticisms of the principle of equal pay for equal work include criticism of the mechanisms used to achieve it and the methodology by which the gap is measured. Some[who?] believe that government actions to correct gender pay disparity serve to interfere with the system of voluntary exchange. They argue the fundamental issue is that the employer is the owner of the job, not the government or the employee. The employer negotiates the job and pays according to performance, not according to job duties. A private business would not want to lose its best performers by compensating them less and can ill afford paying its lower performers higher because the overall productivity will decline. However, the Independent Women's Forum cites another study that prognosticates the wage gap possibly disappearing "when controlled for experience, education, and number of years on the job."
The difference between equal pay for equal work and equal pay for work of equal value
|Equal pay for equal work||Equal pay for work of equal value|
|Equal pay compares the pay of incumbents in the same or very similar jobs.||Pay equity compares the value and pay of different jobs, such as nurse and electrician.|
|Either men or women can complain that their work is undervalued. If a male incumbent is paid less than a female incumbent in the same job, he can file a complaint. As well, a woman can complain if she is paid less than a man in the same job.||Only people (both men and women) in jobs traditionally reserved for women can complain that their work is undervalued. If nurses are paid less than electricians by the same employer, then they can file a complaint.|
The problem which exists in comparing jobs involving different skills with each other is that there are intangibles besides skills and experience which come into play in determining pay. For example, it may take the same level of skills to be an electrician as it does to be a nurse, but if the electrician is performing their job 200 feet above the base floor of an offshore oil rig, pay will tend to be higher because the attendant risks are likewise higher. Indeed, many argue that the unwillingness of women to work in jobs which are dangerous or otherwise undesirable such as plumbing and coal mining accounts for a significant percentage of the wage gap.
