A Complete Guide to Sexual Discrimination in the Workplace
No one takes a job expecting to be treated unfairly because of their gender, but it still happens across all industries and at every level of seniority. Whether it’s a missed promotion or exclusion from other opportunities, offhand comments, or policies that disadvantage one group over another, sex discrimination is unlawful.
This guide helps employers recognise what constitutes sex discrimination, understand their legal obligations under the Equality Act 2010, and implement effective strategies to create a compliant, inclusive workplace.

What Is Classed as Sex Discrimination?
Sex discrimination in the workplace refers to unfair, unequal or less favourable treatment based on a person’s sex or gender. It can affect hiring decisions, pay, promotions, training opportunities,allocation of work and even day-to-day interactions between colleagues. Employers must ensure that their workplace policies, decision-making processes, and culture do not disadvantage employees based on their sex.
Discrimination doesn’t always involve overt hostility or exclusion. It can be subtle, systematic, or even unintended by arising through neutral practices. That said, it still has a significant impact on the individual and the workplace culture as a whole.
Sexual Discrimination: What the Law Says
Under the Equality Act 2010, it’s unlawful to discriminate against someone because of their sex. This applies to all stages of employment: recruitment, employment terms, promotion, dismissal, and beyond. Both men and women are protected under this law. It also applies to employees, workers, applicants and some self-employed.
Sex discrimination can also arise where discriminatory acts (by other employers or employees) are carried out “in the course of employment,” unless employers can show they took all reasonable steps to prevent the conduct.
Failure to comply can lead to costly legal action, as those discriminated may bring claims to the employment tribunal This would ultimately cause reputational damage for the company and therefore should be avoided.
Sex discrimination isn’t limited to direct remarks or decisions but also includes indirect policies or workplace practices that place one sex at a disadvantage without a valid reason. For example, a rule requiring all employees to work full-time might seem neutral. Still, it could disadvantage women, who are statistically more likely to work part-time due to caring responsibilities.
The law also makes it unlawfulto victimise someone for making a complaint about sex discrimination or for supporting someone else’s claim. That protection extends even if the claim isn’t ultimately successful.
Types of Sex Discrimination
Under UK law, there are four main types. Each one works differently but can be equally damaging:
Direct Discrimination
This is the most obvious form. Direct sex discrimination happens when someone is treated less favourably because of their sex. For example, if a woman is overlooked for a promotion in favour of a less-qualified male colleague purely because she’s a woman, that’s direct discrimination.
There is also associative discrimination where someone is treated less favourably because of their association with a person of a particular sex, and perceptive discrimination where someone is treated less favourably because the discriminator holds a mistaken belief about their sex. These are both recognised under direct discrimination and are unlawful.
You must compare the treatment of the discriminated with that of a real or hypothetical person of the opposite sex whose relevant circumstances are not materially different. The question is whether the person discriminated against was treated less favourably because of their sex. The tribunal will draw inferences from the employer’s evidence, policies and treatment of others in the workplace.
It is important to note that unfavourable treatment because of pregnancy or maternity is a distinct claim that does not require consideration of a comparator of the opposite sex who may have been treated differently in the circumstances.
Indirect Discrimination
Indirect discrimination happens when a workplace rule, policy or practice applies to everyone but disproportionately affects one gender compared to the other and can’t be justified or shown to achieve a legitimate aim. A typical example might be a requirement to work late evenings without offering flexible options. While the rule applies to all staff, it may disproportionately disadvantage women, who statistically carry more caring responsibilities. If there’s no legitimate business reason for the policy, it may be unlawful.
Harassment
Sexual harassment is a serious form of discrimination under the Equality Act. It refers to three types, namely:.
- Harassment related to sex: unwanted conduct related to sex that has the purpose or effect of violating dignity or creating an intimidating, hostile, degrading, humiliating or offensive environment.
- Sexual harassment: unwanted conduct of a sexual nature with the same purpose/effect threshold. This can include comments, jokes, messages, images, unwanted touching, or leering.
- Harassment for rejection/submission: less favourable treatment because a person submitted to or rejected sexual harassment or harassment related to sex.
Harassment doesn’t need to be repeated; one incident can be enough. It’s judged based on how the action makes the person feel, not whether the offender thought it was harmless.
Victimisation
Victimisation occurs when someone is mistreated because they’ve made or supported a discrimination complaint. For example, if an employee raises a grievance about sexist comments and is later excluded from meetings or denied opportunities, that may be victimisation. It can also happen to witnesses or colleagues who offer support during a complaint.
This protection still applies whether or not the original complaint succeeds.
Equal Pay and Sex Equality of Terms
Equal pay is a distinct but related regime within the Equality Act. A sex equality clause is implied into contracts, giving a right to equal pay where a woman and a man do:
- Like work;
- Work rated as equivalent under a job evaluation scheme; or
- Work of equal value in terms of demands (skill, effort, decision‑making).
Differences must be justified by a material factor that is not tainted by sex. Equal pay claims can be complex and long‑running; record‑keeping, job evaluation, and pay audits are key.
SexDiscrimination: The Impacts
Discrimination at work goes beyond simply hurting feelings and morale; it can damage careers and finances, too. Below are some of the key ways it plays out in practice.
Career Progression Barriers
A woman may be passed over for promotions or denied leadership opportunities due to assumptions employers or managers may hold about her capabilities or family commitments. Employers risk losing talent and limiting team diversity if progression decisions are influenced by gender-based assumptions.
Unequal Pay
The gender pay gap persists across many industries. Discriminatory pay practices,like offering men higher starting salaries or bigger bonuses for the same role mean women often earn less than male colleagues for equal work. Unjustified pay differences can lead to equal pay claims, reputational damage, and penalties under employment law.
Psychological Harm
Sexual discrimination and harassment can take a toll on mental health. A workplace where discrimination goes unchecked can harm morale, increase absenteeism, and expose employers to mental health-related claims. In some cases, the emotional impact leads people to leave roles or entire careers altogether.
Workplace Culture
Discrimination affects more than just the person on the receiving end. A culture where discrimination is tolerated can damage team cohesion and reduce overall productivity and retention. Productivity suffers, trust in leadership erodes, and the whole team can be impacted.
What Does Sexism in the Workplace Look Like?
Sexual discrimination isn’t always explicit or obvious. Sometimes, it’s subtle, masked as concern, or framed as company policy. But that doesn’t make it any less damaging.
For example, a female project manager returns from maternity leave and is told she’ll no longer be leading high-value accounts ‘to reduce her stress’. The accounts are handed to a junior male colleague without explanation. The decision might sound supportive on the surface, but it denies her the same opportunities based purely on assumptions about her gender and parental responsibilities. That’s discrimination, regardless of the intent behind it, and would be unlawful.
Handling a Sex Discrimination Complaint: A Guide for Employers
Tackling discrimination can feel daunting, but there are clear steps you can take to raise your concerns and protect your rights. Here’s how the process typically works.
Step 1: Keep a Record
Maintain a thorough record of any complaints received, steps taken, and outcomes to demonstrate a fair and consistent process. Save relevant emails, messages, screenshots, or notes, especially if the behaviour is ongoing or part of a broader pattern.
Step 2: Allow Employees to Raise Internally
Ensure employees have clear, accessible reporting channels. Managers should be trained to respond appropriately to concerns.
Step 3: Formal Grievance Processes
Follow your internal grievance process consistently and fairly. Investigate complaints promptly and communicate updates clearly, gather evidence and witness accounts.
As an employer, you’re legally required to follow a fair process, and the employee is entitled to be accompanied to any meetings by a colleague or union rep.
Step 4: ACAS Conciliation
If a complaint progresses, be prepared to participate in ACAS early conciliation. Early resolution can help avoid formal tribunal proceedings. Before making a legal claim, the employee will often contact ACAS for early conciliation. Employers then may be contacted by a conciliator to explore a settlement.
This free, confidential service helps employees and employers resolve disputes without going to a tribunal. The employee is assigned a conciliator who will speak to both sides and try to broker an agreement; this could include financial compensation or changes at work.
Step 5: Legal Action
If no resolution is reached and the employee decides to proceed with a tribunal claim, don’t delay. Employers should seek legal advice promptly if early resolution fails. Proactive engagement can reduce the risk of litigation.
Frequently Asked Questions
What Are Examples of Sex Discrimination in the Workplace?
Workplace sex discrimination can take many forms. It could be direct, like being passed over for promotions due to gender or receiving lower pay than male colleagues for doing the same job. It could also be more subtle, like being treated differently after returning from maternity leave or being given less responsibility because of assumptions about an employee’s personal life.
What Is Classed as Sexual Misconduct at Work?
“Sexual misconduct” is not a defined Equality Act term but is commonly used in policies to capture unwanted sexual behaviour that breaches standards (and may also constitute sexual harassment). Sexual misconduct includes any unwanted behaviour of a sexual nature that makes someone feel uncomfortable, intimidated, or humiliated. This can range from inappropriate comments or jokes to physical contact, unwanted advances, or sharing explicit material.
Final Thoughts
Discrimination doesn’t always come with flashing lights or obvious signs. Sometimes, it creeps in through everyday decisions, conversations, or missed opportunities. Employers must take proactive steps to identify and prevent sexual discrimination before it becomes a legal issue or damages workplace culture.
