United Kingdom employment equality law is a body of law which legislates against prejudice-based actions in the workplace. As an integral part of UK labour law it is unlawful to discriminate against a person because they have one of the "protected characteristics", which are, age, disability, gender reassignment, marriage and civil partnership, race, religion or belief, sex, pregnancy and maternity, and sexual orientation. The primary legislation is the Equality Act 2010, which outlaws discrimination in access to education, public services, private goods and services, transport or premises in addition to employment. This follows three major European Union Directives, and is supplement by other Acts like the Protection from Harassment Act 1997. Furthermore, discrimination on the grounds of work status, as a part-time worker, fixed term employee, agency worker or union membership is banned as a result of a combination of statutory instruments and the Trade Union and Labour Relations (Consolidation) Act 1992, again following European law. Disputes are typically resolved in the workplace in consultation with an employer or trade union, or with advice from a solicitor, ACAS or the Citizens Advice Bureau a claim may be brought in an employment tribunal. The Equality Act 2006 established the Equality and Human Rights Commission, a body designed to strengthen enforcement of equality laws.
Discrimination is unlawful when an employer is hiring a person, in the terms and conditions of contract that are offered, in making a decision to dismiss a worker, or any other kind of detriment. "Direct discrimination", which means treating a person less favourably than another who lacks the protected characteristic, is always unjustified and unlawful, with the exception of age. It is lawful to discriminate against a person because of their age, however, only if there is a legitimate business justification accepted by a court. Where there is an "occupational requirement" direct discrimination is lawful, so that for instance an employer could refuse to hire a male actor to play a female role in a play, where that is indispensable for the job. "Indirect discrimination" is also unlawful, and this exists when an employer applies a policy to their workplace that affects everyone equally, but it has a disparate impact on a greater proportion of people of one group with a protected characteristic than another, and there is no good business justification for that practice. Disability differs from other protected characteristics in that employers are under a positive duty to make reasonable adjustments to their workplace to accommodate the needs of disabled staff. For age, belief, sex, race, gender reassignment and sexuality there is generally no positive obligation to promote equality, and positive discrimination is generally circumscribed by the principle that merit must be regarded as the most important characteristic of a person. In the field of equal pay between men and women, the rules differ in the scope for comparators. Any dismissal because of discrimination is automatically unfair and entitles a person to claim under the Employment Rights Act 1996 section 94 no matter how long they have worked.
Anti-discrimination law is a recent development. Religious discrimination was first tackled by laws aimed at Roman Catholics. The Papists Act 1778 was the first act that addressed legal discrimination against Roman Catholics, but it was not until the Roman Catholic Relief Act 1829 that Catholics were considered fully emancipated. A year later, in 1830, debates began on the subject of making similar provisions for Jews. A strong Tory lobby in Parliament prevented any furtherance of this cause until the Religious Opinions Act 1846, although this only went some way towards acceptance of all religious viewpoints. It was only the Reform Act 1867 that saw extension of the vote to every male householder. Women were also marginalised from general social participation. The first changes came at municipal level, particular in the Birmingham Municipal Council from the 1830s. The Chartists from the mid 19th century, and the Suffragettes after the turn of the 20th century lobbied for universal suffrage against a conservative judiciary and a liberal political establishment. In Nairn v The University Court of the University of St Andrews (1907), Lord McLaren even proclaimed that it is
"a principle of the unwritten constitutional law of this country that men only were entitled to take part in the election of representatives to Parliament."
The Representation of the People Act 1918 gave the universal franchise to men, and knocked away the last barriers of wealth discrimination for the vote. But for women, only those over 30 were enfranchised, and the judiciary remained as conservative as ever. In Roberts v Hopwood (1925) a metropolitan borough council had decided to pay its workers a minimum of £4 a week, whether they were men or women and regardless of the job they did. The House of Lords approved the district auditor's surcharge for being overly gratuitous, given the fall in the cost of living. Lord Atkinson said
"the council would, in my view, fail in their duty if ... [they] allowed themselves to be guided in preference by some eccentric principles of socialistic philanthropy, or by a feminist ambition to secure the equality of the sexes in the matter of wages in the world of labour."
Though Lord Buckmaster said
"Had they stated that they determined as a borough council to pay the same wage for the same work without regard to the sex or condition of the person who performed it, I should have found it difficult to say that that was not a proper exercise of their discretion."
After a decade, the Representation of the People Act 1928 finally gave women the vote on an equal footing.
The Sex Disqualification (Removal) Act 1919 received Royal Assent on 23 December 1919. Its basic purpose was "… to amend the Law with respect to disqualification on account of sex" "from the exercise of any public function, or from being appointed to or holding any civil or judicial office or post, or from entering or assuming or carrying on any civil profession or vocation, or for admission to any incorporated society (whether incorporated by Royal Charter or otherwise)".
Attitudes to racial prejudice in the law were set to change markedly with the proverbial "winds of change" sweeping through the Empire after World War II. As Britain's colonies won independence, many immigrated to the motherland, and for the first time communities of all colours were seen in London and the industrial cities of the North. The Equal Pay Act 1970, the Sex Discrimination Act 1975 and the Race Relations Act 1976 were passed by Harold Wilson's Labour government.
In 1975, Britain became a member of the European Community, which became the European Union in 1992 with the agreement of the Maastricht Treaty. The Conservative government opted out of the Social Chapter of the treaty, which included provisions on which anti-discrimination law would be based. Although they passed the Disability Discrimination Act 1995, it was not until Tony Blair's "New Labour" government won the 1997 election that the UK opted into the social provisions of EU law. In 2000, the EU overhauled and introduced new Directives explicitly protecting people with a particular sexuality, religion, belief and age, as well as updating the protection against disability, race and gender discrimination. The law is therefore quite new and is still in a state of flux. Between the EU passing directives and the UK government implementing them, it is apparent that the government has often failed to offer the required minimum level of protection. More changes are likely soon to iron out the anomalies.
Equality legislation in the UK, formerly in separate Acts and regulations for each protected characteristic, is now primarily found in the Equality Act 2010. Particularly since the United Kingdom joined the Social Chapter of the European Union treaties, it mirrors a series of EU Directives. The three main Directives are the Equal Treatment Directive (Directive 2006/54/EC, for gender), the Racial Equality Directive (2000/48/EC) and the Directive establishing a general framework for equal treatment in employment and occupation (2000/78/EC, for religion, belief, sexuality, disability and age).
Direct discrimination occurs when an employer treats someone less favourably on the ground of a protected characteristic. It is unlawful under section 13 of the Equality Act 2010. A protected characteristic (age, disability, gender reassignment, marriage and civil partnership, race, religion or belief, sex, and sexual orientation) must be the reason for the different treatment, so that it is because of that characteristic that the less favourable treatment occurs. Generally, the law protects everyone, not just a group perceived to suffer discrimination. Therefore, it is unlawful to treat a man less favourably than a woman, or a woman less favourably than a man, on the ground of the person's sex. However people who are single are not protected against more favourable treatment of people in marriage or civil partnership, and non disabled people are not protected if a disabled person is treated more favourably.
In Coleman v Attridge Law in the European Court of Justice confirmed that a person may claim discrimination even if they are not the person with the protected characteristic, but rather they suffer unfavourable treatment because of someone they associate with.
For the protected characteristic of Age, it is a defence to a claim of direct discrimination that the discrimination is "justified" by some reason. There is no defence of justification for other protected characteristics.
Under the Equality Act 2010 section 26, a person harasses another if he or she engages in unwanted conduct related to a relevant protected characteristic, and the conduct has the purpose or effect of violating the other's dignity, or creating an intimidating, hostile, degrading, humiliating or offensive environment for the other. It is also harassment if a person treats another less favourably because the other has rejected or submitted to unwanted conduct of a sexual nature.
The definition of "victimisation" is found in the Equality Act 2010 section 27. It refers to subjecting a person to a further detriment after they try to complain or bring proceedings in connection with discrimination, on their own behalf or on behalf of someone else.
"Indirect" discrimination is unlawful under the Equality Act 2010 section 19. It involves the application of a provision, criterion or practice to everyone, which has a disproportionate effect on some people and is not objectively justified. For instance, a requirement that applicants for a job be over a certain height would have a greater impact on women than on men, as the average height of women is lower than that of men. It is a defence for the employer to show that the requirement is “a proportionate means of achieving a legitimate aim”.

Discrimination law is "blind" in that motive is irrelevant to discrimination and both minorities or majorities could make discrimination claims if they suffer less favourable treatment. Positive discrimination (or "affirmative action" as it is known in the US) to fill up diversity quotas, or for any other purpose, is prohibited throughout Europe, because it violates the principle of equal treatment just as much as negative discrimination. There is, however, a large exception. Suppose an employer is hiring new staff, and they have 2 applications where the applicants are equally qualified for the job. If the workforce does not reflect society's makeup (e.g. that women, or ethnic minorities are under-represented) then the employer may prefer the candidate which would correct that imbalance. But they may only do so where both candidates are of equal merit, and further conditions must be met. This type of measure is also known as positive action. Sections 158 and 159 Equality Act 2010 set out the circumstances in which positive action is allowed. Section 159, which deals with positive action in connection with recruitment and promotion (and which is the basis for the example of equally qualified applicants above), did not come into force until April 2011. The Government Equalities Office has issued a guide to the Section 159 rules. Section 158 deals with the circumstances in which positive action is permitted other than in connection with recruitment and promotion, for example in provision of training opportunities. Section 158 does not have the requirement for candidates to be equally qualified.
The normal types of claim apply to disability, but additional types of claim are particular to it. These are 'discrimination arising from disability' and the reasonable adjustment duty. "Discrimination arising from disability" was a newly formulated test introduced after the House of Lords decision in Lewisham LBC v Malcolm and EHRC was felt to have shifted the balance of protection too far away from disabled people. Section 15 Equality Act 2010 creates a broad protection against being treated unfavourably "because of something arising in consequence of" the person's disability, but subject to the employer having an 'objective justification' defence if it shows its action was a proportionate means of achieving a legitimate aim. There is also a 'knowledge requirement', in that the employer has a defence if it shows it did not know, and could not reasonably be expected to know, that the person had the disability. Section 15 will apply, for example, where a disabled person is dismissed because of a long absence from work which resulted from their disability - the issue will be whether the employer can show the 'objective justification' defence applies (assuming the 'knowledge requirement' is met).
The reasonable adjustment duty is particularly important. The duty can apply where a disabled person is put at a 'substantial' disadvantage in comparison with non-disabled people by a 'provision, criterion or practice' or by a physical feature. The employer's obligation is, broadly, to take such steps as it is reasonable to have to take to avoid the disadvantage (s 20 Equality Act 2010). 'Substantial' means only more than minor or trivial (s 212(1) Equality Act 2010). A further strand of the duty can require an employer to provide an auxiliary aid or service (s 20(5) Equality Act 2010). There are provisions dealing with employer's lack of knowledge of the disability (Equality Act 2010 Sch 8 para 20).
Employers should actively pursue policies to accommodate protected groups into the workforce. This duty is made explicit in law for pregnant women and for people who are disabled. For people with religious sensitivities, particularly the desire to worship during work cases show there is no duty, but employers should apply their minds to accommodating their employee's wishes even if they ultimately decide not to.
The main outcome of the Equality Act 2006 was the establishment of a new Equality and Human Rights Commission, subsuming specialist bodies from before. Its role is in research, promotion, raising awareness and enforcement of equality standards. For lawyers, the most important work of predecessors has been strategic litigation (advising and funding cases which could significantly advance the law) and developing codes of best practice for employers to use. Around 20,000 discrimination cases are brought each year to UK tribunals.
Under the Equality Act 2010 Sch 9, a number of defences are available to employers who have policies which discriminate. An "occupational requirement" refers to exceptions to the prohibition on direct discrimination. An example could be a theatre requiring an actor of Black African origin to play a Black African character. An employer has the burden of showing that they genuinely need somebody of a particular gender, race, religion, etc., for the job. These exceptions are few.
Under section 23 of the Equality Act, in order to show that there has been discrimination, the claimant must show that there is no material difference between the claimant and the other person, or "comparator", who does not share the same protected characteristic. If the respondent can show that there is another cause for the different treatment, not related to the protected characteristic, then the claim will fail.
It is a defence to a claim of unlawful indirect discrimination, and also to a claim of direct discrimination on the ground of age, that the discriminatory act is "a proportionate means of achieving a legitimate aim" (sections 13(2) and 19).
People with a protected characteristic are protected from discrimination in employment, and in access to services, education, premises, and associations. Examples of prohibited discrimination include as customers, in social security, access to education and other public services. The UK Labour Government codified and strengthened the disparate heads of protection into a single act, namely the Equality Act 2010.
In the UK, equality between sexes has been a principle of employment law on since the 1970s, when the Equal Pay Act 1970 and the Sex Discrimination Act 1975 were introduced. Also, in 1972, the UK joined the European Community (now the EU). Article 141(1) of the Treaty of the European Community states,
"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."

In the Weaver v NATFHE race discrimination case (also known as the Bournville College Racial Harassment issue), an Industrial Tribunal decided that the trade union NATFHE was entitled to apply its rule that a members' case against another member would not be supported if it put that member's tenure at risk.

Sexuality and gender reassignment
Sexual orientation and gender reassignment status are both covered by the Equality Act 2010.
Some protection for trans gender people was provided by the Sex Discrimination (Gender Reassignment) Regulations 1999, which added "Gender reassignment" to the coverage of the Sex Discrimination Act 1975. Sexual orientation was covered from 1 December 2003 until 2010 by the Employment Equality (Sexual Orientation) Regulations 2003, SI 2003/1661, and by the Equality Act (Sexual Orientation) Regulations.
Religion or belief
While direct discrimination on grounds of religion or belief is automatically unlawful, the nature of religions or beliefs leads to the conclusion that objective justification for disparate impact is easier. Beliefs often lead adherents to the need to manifest their closely held views, in a way which may conflict with ordinary requirements of the work place. There is not the same degree of privilege granted to beliefs as is to a disability, requiring "reasonable adjustments" for the wishes of the believer. So in cases where an adherent to a religion wishes to take time off to pray, or wear a particular article of clothing or jewellery, it will usually be within the right of the employer to insist that the contract of employment is performed as was initially agreed. This refusal of the law to grant privileged status to beliefs may reflect the element of choice in belief or the need of a secular society to treat all people, whether believers or not, equally.
Discrimination on grounds of religion was previously covered in an ad hoc way for Muslims and Sikhs through the race discrimination provisions. The new regulations were introduced to comply with the EU Framework Directive 2000/78/EC on religion or belief, age, sexuality and disability.

Work status protection
More recently, two measures have been introduced, and one has been proposed, to prohibit discrimination in employment based on atypical work patterns, for employees who are not considered permanent. The Part-time Workers Regulations and the Fixed-term Employee Regulations were partly introduced to remedy the pay gap between men and women. The reason is, women are far more likely to be doing non-full-time permanent jobs. However following the Treaty of Amsterdam, a new Article 13 promised Community action to remedy inequalities generally. The abortive Agency Workers Directive was meant to be the third pillar in this programme. Discrimination against union members is also a serious problem, for the obvious reason that some employers view unionisation as threat to their right to manage.
