Employment Law – Sex Discrimination

What is Sex Discrimination?

Sex discrimination occurs where someone experiences unlawful treatment because of their sex.

Sex is one of the protected characteristics under the Equality Act 2010.

Sex discrimination can affect both women and men and can arise at any stage of employment.

There are four principal forms of sex discrimination:

• Direct discrimination
• Indirect discrimination
• Harassment
• Victimisation

Separate provisions also protect employees against sexual harassment.

Discrimination can occur in relation to matters such as:

• Recruitment
• Pay and benefits
• Training
• Promotion
• Working arrangements
• Performance management
• Disciplinary action
• Redundancy
• Dismissal

How is Sex Defined Under the Equality Act?

The Equality Act 2010 defines the protected characteristic of sex by reference to a person being a man or a woman.

In For Women Scotland Ltd v Scottish Ministers [2025] UKSC 16, the Supreme Court held that the terms "sex", "man" and "woman" in the Equality Act refer to biological sex.

This means that, for the purposes of the protected characteristic of sex under the Equality Act:

• Woman refers to a biological female
• Man refers to a biological male

This interpretation applies even where a person has a Gender Recognition Certificate.

However, this does not remove Equality Act protection from transgender people.

A transgender person may have separate protection because of the protected characteristic of gender reassignment and can also, depending on the circumstances, bring claims involving perceived sex or other applicable Equality Act provisions.

For further guidance, see Gender Reassignment Discrimination.

Who is Protected by Sex Discrimination Law?

Equality Act employment protection is not limited to permanent employees.

Depending on the circumstances, it can protect:

• Employees
• Workers
• Job applicants
• Agency workers
• Contractors required personally to perform work
• Certain self-employed people who personally provide their services
• Apprentices and trainees
• Office holders
• Partners
• Former employees in relation to certain post-employment treatment

A genuinely independent self-employed person operating their own business will not automatically fall within the employment provisions of the Equality Act.

Protection can apply throughout the employment relationship, including:

• Advertising a job
• Recruitment
• Interviews
• Terms of employment
• Promotion
• Training
• Benefits
• Disciplinary procedures
• Redundancy
• Dismissal
• References

Direct Sex Discrimination

Direct discrimination occurs where one person treats another less favourably because of sex.

For example, direct sex discrimination could potentially occur where a suitably qualified woman is refused promotion because the employer prefers a man in the role.

The same principle applies in reverse.

A male employee can also bring a sex discrimination claim where he is treated less favourably because he is a man.

Direct sex discrimination can therefore occur:

• Against a woman by a man
• Against a woman by another woman
• Against a man by a woman
• Against a man by another man

The sex of the person carrying out the discrimination does not determine whether the treatment is unlawful.

Does the Employer Have to Intend to Discriminate?

No.

Direct discrimination does not require an employer to admit:

• Prejudice
• Hostility
• An intention to discriminate

The important question is why the employee was treated less favourably.

Unconscious stereotypes and assumptions can therefore be relevant.

For example, an employer might assume that a woman with young children will be less committed to a senior role.

Even if the employer believes it is acting helpfully, a decision made because of sex can still potentially be discriminatory.

Can Direct Sex Discrimination Be Justified?

Ordinary direct sex discrimination cannot generally be objectively justified.

This differs from indirect discrimination, where an employer can potentially defend a discriminatory provision, criterion or practice by demonstrating that it is a proportionate means of achieving a legitimate aim.

However, the Equality Act contains specific statutory exceptions in limited circumstances.

What About Special Treatment Connected With Pregnancy or Childbirth?

The Equality Act specifically recognises that special treatment can lawfully be provided to women in connection with:

• Pregnancy
• Childbirth

A man cannot ordinarily establish direct sex discrimination merely because a woman received lawful special treatment connected with pregnancy or childbirth.

Pregnancy and maternity also have their own separate protected characteristic and specific statutory protections.

For further guidance, see Pregnancy Discrimination and Maternity Pay and Leave.

Indirect Sex Discrimination

Indirect discrimination can occur where an employer applies a provision, criterion or practice, commonly called a PCP, to everyone but it places people of one sex at a particular disadvantage compared with people of the other sex.

The PCP may appear neutral.

The discriminatory effect becomes apparent when its impact is considered.

For example, an employer might require all employees to work particular hours that disproportionately disadvantage women because women as a group may still be more likely to have primary childcare responsibilities.

Another example could be an unnecessary minimum-height requirement that disproportionately excludes women.

Indirect discrimination will not necessarily be unlawful if the employer can objectively justify the PCP.

What is Objective Justification?

An employer can defend indirect sex discrimination if it proves that the PCP is a proportionate means of achieving a legitimate aim.

This requires more than simply identifying a convenient business reason.

The employer should normally demonstrate:

• A Genuine legitimate aim
• A Connection between the PCP and that aim
• That the measure is reasonably necessary
• That less discriminatory alternatives were properly considered
• That the discriminatory effect is proportionate to the objective

Potential legitimate aims can include genuine matters such as:

• Operational requirements
• Health and safety
• Service delivery
• Staffing needs
• Business efficiency

Cost can be relevant to an employer's decision-making, but an employer should not assume that saving money alone will automatically justify discriminatory treatment.

The Tribunal will assess proportionality in the circumstances.

Can Full-Time Working Requirements Be Indirectly Discriminatory?

Potentially.

An employer can require a role to be full-time where it has genuine business reasons for doing so.

However, a blanket refusal to consider:

• Part-time work
• Adjusted hours
• Other flexible arrangements

may place women at a particular disadvantage and could potentially amount to indirect sex discrimination unless objectively justified.

The particular role and operational requirements will be important.

Separately, eligible employees have statutory rights in relation to flexible working requests.

Who Can Be Liable for Sex Discrimination?

An employer can be liable for its own discriminatory decisions.

It may also be liable for discriminatory acts committed by employees in the course of employment.

This is commonly known as vicarious liability.

For example, an employer may potentially be liable for discriminatory conduct by:

• A Manager
• A Supervisor
• A Colleague

The individual who committed the discrimination can also potentially be personally liable under the Equality Act.

A claim may therefore sometimes be brought against:

• The Employer
• The Individual discriminator
• Both

Can an Employer Defend a Vicarious Liability Claim?

Potentially.

An employer may have a statutory defence if it can show that it took all reasonable steps to prevent the employee from committing the discriminatory act or acts of that description.

Relevant steps can include:

• Effective equality policies
• Appropriate staff training
• Refresher training
• Proper reporting procedures
• Effective investigation of complaints
• Enforcement of workplace standards

Simply having an equality policy stored on an internal system will not necessarily be enough.

The Tribunal will consider what reasonable preventative measures were available in the circumstances.

When Can Different Treatment Because of Sex Be Lawful?

There are limited exceptions under the Equality Act.

Two important areas are:

• Occupational requirements
• Positive action

Occupational Requirements

In limited circumstances, being a particular sex can be a genuine occupational requirement.

The employer must show that:

• Having the characteristic is genuinely an occupational requirement
• Applying that requirement is a proportionate means of achieving a legitimate aim

For example, requiring a female worker may potentially be lawful for a role involving intimate personal care of women where considerations of privacy and dignity make the requirement objectively necessary.

The exception is narrow.

An employer cannot normally restrict a job to men or women merely because:

• Customers prefer it
• It reflects a stereotype
• The employer believes one sex will perform better

Positive Action

The Equality Act permits certain forms of positive action designed to address disadvantage or under-representation.

For example, an employer may in appropriate circumstances:

• Provide targeted training
• Encourage applications from an under-represented sex
• Provide development opportunities to address a disadvantage

Different and more limited rules apply when actually selecting someone for recruitment or promotion.

An employer may potentially use a protected characteristic as a tie-break where candidates are genuinely of equal merit and the statutory conditions are satisfied.

For example, where women are disproportionately under-represented in a particular role, an employer may in appropriate circumstances prefer a woman over an equally qualified man.

However, positive action does not generally allow an employer to:

• Automatically prefer all women
• Operate quotas
• Appoint a less suitable candidate merely because of sex

That could amount to unlawful positive discrimination.

How Do I Bring a Sex Discrimination Claim?

If you believe you have experienced sex discrimination, you may wish to try to resolve the matter internally.

Depending on the circumstances, you can:

• Raise the issue informally
• Speak to your manager
• Speak to Human Resources
• Raise a formal grievance

If the matter cannot be resolved internally, you may be able to bring an Employment Tribunal claim.

It is not necessary to wait until an internal grievance or appeal has finished before protecting your Tribunal position.

This is important because internal procedures do not normally stop the Tribunal limitation period.

For further guidance, see Grievance at Work.

Do I Have to Complete the Grievance Procedure Before Going to Tribunal?

No.

It can often be sensible to use the employer's grievance process, but you do not normally have to complete every internal stage before beginning an Employment Tribunal claim.

You must keep the legal deadline under review.

Before presenting most Employment Tribunal claims, you must normally notify Acas and begin Early Conciliation.

Acas Early Conciliation can affect the calculation of the final Tribunal deadline.

Can Sex Discrimination Lead to Constructive Dismissal?

Potentially.

If discriminatory conduct is sufficiently serious, it could form part of a fundamental breach of the employment contract.

An employee might then consider resigning and alleging Constructive Dismissal.

However, discrimination does not automatically establish constructive dismissal.

The employee would still need to satisfy the separate contractual requirements of a constructive dismissal claim.

Resigning can materially affect legal rights and should therefore be considered carefully.

As at 10 September 2026, an ordinary constructive unfair dismissal claim will generally require 2 years' continuous employment, subject to exceptions.

From 1 January 2027, the ordinary unfair dismissal qualifying period will reduce to 6 months.

There is no comparable minimum service requirement for a sex discrimination claim.

Remedies for Sex Discrimination

If an Employment Tribunal finds that unlawful sex discrimination occurred, it can potentially provide one or more of the following remedies:

• A Declaration
• Compensation
• A Recommendation

Declaration

A declaration formally records the legal rights of the parties and the Tribunal's finding that unlawful discrimination occurred.

Compensation

Compensation is intended, so far as money can do so, to compensate the claimant for loss and injury caused by the discrimination.

Recommendation

The Tribunal can make an appropriate recommendation requiring the respondent to take specified steps within a stated period to reduce the adverse effect of the discrimination on the claimant.

What Compensation Can You Claim for Sex Discrimination?

Compensation for sex discrimination is generally uncapped.

Unlike ordinary unfair dismissal compensation, there is no general statutory ceiling on an Equality Act discrimination award.

Depending on the circumstances, compensation can potentially include:

• Past loss of earnings
• Future loss of earnings
• Lost holiday pay
• Lost bonus or commission
• Lost benefits
• Pension loss
• Injury to feelings
• Psychiatric or physical injury
• Aggravated damages in appropriate cases
• Interest

A claimant will normally be expected to take reasonable steps to reduce or mitigate continuing financial losses.

What is Injury to Feelings Compensation?

An injury-to-feelings award compensates for the emotional impact of unlawful discrimination.

This can include:

• Humiliation
• Distress
• Anxiety
• Upset
• Frustration
• Loss of confidence
• Emotional suffering

The amount depends on the impact of the discrimination rather than simply the number of incidents.

Employment Tribunals use the Vento bands as guidance.

What Are the Current Vento Bands?

For claims presented on or after 6 April 2026, the Vento bands are:

• Lower band – £1,300 to £12,600
• Middle band – £12,600 to £37,700
• Upper band – £37,700 to £62,900

The most exceptional cases can justify an award exceeding £62,900.

The lower band generally applies to less serious cases.

The middle band applies to cases that do not merit an upper-band award.

The upper band is reserved for the most serious cases.

Can Aggravated Damages Be Awarded?

Potentially.

Aggravated damages may be appropriate in some cases where the way the respondent behaved made the claimant's injury more serious.

This can potentially include particularly:

• High-handed behaviour
• Malicious conduct
• Insulting conduct

However, aggravated damages are not automatically awarded simply because discrimination was deliberate.

What About Punitive or Exemplary Damages?

Exemplary damages are exceptionally rare in employment discrimination cases.

They are not a routine additional punishment for an employer that has discriminated.

Whether such damages are legally available depends on the particular circumstances and the applicable legal principles.

They should not be treated as a normal component of a sex discrimination award.

Can I Claim for Personal Injury Caused by Discrimination?

You cannot ordinarily bring a standalone negligence-based personal injury claim in the Employment Tribunal.

However, if unlawful sex discrimination causes a recognised:

• Psychiatric injury
• Physical injury

compensation for that injury can potentially form part of the Equality Act award.

Psychiatric injury is different from injury to feelings.

For example, discriminatory treatment might cause emotional distress that justifies an injury-to-feelings award but does not amount to a medically recognised psychiatric condition.

In a more serious case, medical evidence may establish a recognised psychiatric injury as well.

The Tribunal must avoid awarding compensation twice for the same harm.

How is Psychiatric Injury Assessed?

Factors can include:

• Ability to cope with life
• Ability to work
• Effect on family relationships
• Effect on social relationships
• Treatment received
• Likely success of treatment
• Future vulnerability
• Prognosis
• Whether medical assistance has been required
• Nature and duration of the conduct that caused the injury

Compensation can include:

General Damages

These may compensate for:

• Pain and suffering
• Psychiatric injury
• Loss of amenity

Financial Losses

These can include quantifiable losses such as:

• Lost earnings
• Medical or treatment expenses
• Other losses caused by the injury

Medical evidence is often particularly important where a recognised psychiatric injury is claimed.

What Can I Not Normally Claim?

Certain remedies are not automatically available merely because discrimination has been established.

For example:

• A Tribunal does not normally order an apology as a standalone remedy
• Separate injury-to-feelings awards are not automatically made for every individual discriminatory incident
• Legal costs are not routinely awarded simply because a claimant wins
• A claimant cannot receive double compensation for the same injury or loss

Costs can nevertheless be awarded in particular circumstances, including where a party or representative has acted unreasonably or pursued a case with no reasonable prospect of success.

There is also no automatic standalone compensation category for loss of reputation, although a claimant may potentially recover provable financial loss caused by discriminatory treatment where the legal requirements are satisfied.

How Do You Prove Sex Discrimination?

Direct evidence of sex discrimination is often unavailable.

An employer will rarely state openly that a decision was made because someone is a woman or a man.

Evidence may instead include:

• Emails
• Messages
• Comments
• Recruitment records
• Interview notes
• Performance records
• Promotion decisions
• Pay information
• Treatment of comparable employees
• Changes in the employer's explanation
• Witness evidence

The Equality Act uses a burden-of-proof framework.

Initially, the claimant must establish facts from which the Tribunal could decide, in the absence of another explanation, that unlawful discrimination occurred.

If sufficient facts are established, the burden shifts to the respondent to prove that it did not commit the unlawful discrimination.

The Tribunal determines disputed facts on the balance of probabilities.

Is Different Treatment Between a Man and Woman Enough?

Not necessarily.

Showing that:

• A Woman was treated negatively
• A Man was treated more favourably

can be relevant evidence, but does not automatically prove that sex caused the difference.

The employer may have a genuine non-discriminatory explanation.

The Tribunal considers the evidence as a whole and asks why the treatment occurred.

Raising a Grievance

If you are still employed and cannot resolve the issue informally, you may wish to raise a formal grievance.

The grievance should normally identify:

• What happened
• When it happened
• Who was involved
• Why you believe sex was relevant
• Relevant evidence
• Witnesses
• What outcome you are seeking

Your employer should investigate the complaint fairly and without unreasonable delay.

You can still potentially bring an Employment Tribunal claim while remaining employed.

Does a Grievance Extend the Tribunal Deadline?

No.

An internal:

• Grievance
• Investigation
• Appeal

does not normally pause the legal time limit for bringing a discrimination claim.

Acas Early Conciliation has separate statutory rules that can pause the limitation clock.

Time Limits

Employment Tribunal time limits are strict.

As at 10 September 2026, most sex discrimination claims must generally be started within:

3 months minus 1 day

from the discriminatory act complained about.

Where the claim involves several acts, the time-limit analysis can become more complicated.

Before submitting most Tribunal claims, you must normally notify Acas for Early Conciliation.

For further guidance, see Employment Tribunal Proceedings.

What if the Discrimination Continued Over Time?

Conduct extending over a period can potentially be treated as occurring at the end of that period.

For example, this might apply to:

• An Ongoing discriminatory policy
• A Continuing discriminatory practice
• A Connected course of discriminatory conduct

However, separate decisions do not automatically become one continuing act merely because each is alleged to involve sex discrimination.

Whether conduct amounts to an act extending over a period depends on the circumstances.

For further guidance, see Continuing Acts of Discrimination.

Are the Tribunal Time Limits Changing?

Yes.

From 1 October 2026, the time limit for most Employment Tribunal claims will increase to:

6 months minus 1 day

The new period applies where the relevant time limit starts on or after 1 October 2026.

Where the limitation period began before that date, the existing rules will generally continue to apply.

You should therefore calculate the actual deadline rather than assuming that every claim automatically has six months from October.

Can a Late Sex Discrimination Claim Be Allowed?

Potentially.

An Employment Tribunal has discretion to extend the normal Equality Act deadline where it considers that doing so is just and equitable.

Relevant factors can include:

• Length of the delay
• Reason for the delay
• Effect on available evidence
• Prejudice to each party
• When relevant facts became known
• Steps taken to obtain advice

An extension is discretionary and should not be relied upon.

Further Sex Discrimination Issues

Can Men Experience Sex Discrimination?

Yes.

Sex discrimination against men is just as capable of being unlawful as discrimination against women.

For example, an employer could potentially discriminate against a male employee if it assumes that:

• Men should not have childcare responsibilities
• Men should not work flexibly
• A Particular role is more suitable for women

The relevant legal test applies regardless of which sex is disadvantaged.

Can an Employer Prioritise Flexible Working Requests From Women?

An employer should not automatically prioritise a woman's flexible working request simply because she is a woman.

Doing so could potentially amount to direct sex discrimination against a male employee whose request is treated less favourably because he is male.

Each request should be considered appropriately.

At the same time, an employer should consider whether refusing a particular working arrangement could itself indirectly disadvantage women and, if so, whether that disadvantage is objectively justified.

Can an Employer Ask a Woman Whether She Plans to Have Children?

Employers should avoid making recruitment or promotion decisions based on assumptions about:

• Pregnancy
• Childbirth
• Family plans
• Childcare responsibilities

Asking only female candidates whether they intend to have children can provide evidence of discriminatory assumptions, particularly where the answer influences the recruitment decision.

The legal issue is not simply the fact that a question was asked, but whether sex, pregnancy or related assumptions affected the treatment or decision.

An employer should generally ask candidates questions relevant to their ability to perform the role rather than making assumptions based on family plans.

What if Sexist Behaviour is Described as a Joke?

The person carrying out harassment does not avoid liability simply by saying:

• It was only a joke
• They did not mean to offend anyone

When deciding whether unwanted conduct had the prohibited effect, the Tribunal considers:

• The Claimant's perception
• Other circumstances of the case
• Whether it was reasonable for the conduct to have that effect

Intent can be relevant, but it is not the only consideration.

Pregnancy, Maternity and Redundancy

Pregnancy and maternity have their own Equality Act protection in addition to wider sex discrimination law.

There are also special statutory redundancy protections.

As at September 2026, qualifying redundancy protection extends beyond someone who is currently on maternity leave.

For pregnancy and maternity cases, the protected period generally:

• Starts when the employee tells the employer they are pregnant
• Continues during maternity leave
• Ends 18 months after the exact date of birth

Where a suitable alternative vacancy exists during the protected period, the employer must generally offer it to the protected employee as a priority over employees who do not have equivalent statutory priority.

Protection also applies in specified circumstances to employees taking:

• Adoption leave
• Shared parental leave
• Neonatal care leave
• Bereaved partner's paternity leave

This priority relates to suitable alternative vacancies.

It does not automatically exempt a pregnant employee or employee on maternity leave from a fair selection process where an employer is simply reducing the number of existing roles.

For further guidance, see Pregnancy Discrimination, Maternity Pay and Leave and Redundancy.

Harassment Related to Sex

Harassment related to sex is prohibited under the Equality Act.

It occurs where there is unwanted conduct related to sex that has the purpose or effect of:

• Violating a person's dignity
• Creating an intimidating environment
• Creating a hostile environment
• Creating a degrading environment
• Creating a humiliating environment
• Creating an offensive environment

Examples might include persistent comments based on stereotypes about:

• Women
• Men
• How a man or woman should behave

Harassment does not have to be specifically directed at the person bringing the complaint.

A workplace culture involving repeated sexist comments can potentially create an unlawful environment for others who hear or experience them.

Sexual Harassment

Sexual harassment is legally distinct from harassment related to sex.

Sexual harassment occurs where someone engages in unwanted conduct of a sexual nature and the conduct has the purpose or effect of:

• Violating another person's dignity
• Creating an intimidating environment
• Creating a hostile environment
• Creating a degrading environment
• Creating a humiliating environment
• Creating an offensive environment

Potential examples can include:

• Unwanted sexual comments
• Sexual jokes
• Unwanted touching
• Sexual messages
• Displaying sexual material
• Unwanted propositions

There is also separate protection where a person is treated less favourably because they:

• Rejected sexual harassment
• Submitted to sexual harassment
• Rejected or submitted to certain sex-related harassment

For further guidance, see Sexual Harassment at Work.

Does My Employer Have a Duty to Prevent Sexual Harassment?

Yes.

As at 10 September 2026, employers have a statutory duty to take reasonable steps to prevent sexual harassment of their workers in the course of employment.

This is a preventative duty.

Employers should therefore consider measures such as:

• Assessing harassment risks
• Having effective policies
• Training managers and staff
• Providing reporting routes
• Responding appropriately to complaints

From 30 October 2026, this duty will strengthen so that employers must take all reasonable steps to prevent sexual harassment.

The change is introduced by the Employment Rights Act 2025.

Victimisation

Victimisation occurs where someone suffers a detriment because they have done, or it is believed they have done or may do, a protected act under the Equality Act.

Protected acts can include:

• Complaining about sex discrimination
• Raising a grievance
• Bringing an Equality Act claim
• Supporting another person's complaint
• Giving evidence in discrimination proceedings
• Making an allegation that someone breached the Equality Act

For example, it could amount to victimisation if an employer excludes an employee from promotion opportunities because they previously supported a colleague's sex discrimination complaint.

The employee does not need to identify another person who was treated differently.

Protection does not normally apply to false evidence or allegations made in bad faith.
