Sexism in the Workplace: Understanding Legal Obligations for Employers

Sexism has no place in the modern UK workplace - and yet, many employers still find themselves grappling with complaints, uncertainty, or even costly tribunal claims tied to sexist behaviours, pay gaps, or outdated processes. Whether you’re hiring your first employee or leading a growing business, knowing what constitutes sexism and understanding your legal obligations as an employer is absolutely essential.

If you’re feeling unsure about the rules, or you want to make sure your business is fully protected (and a truly fair place to work), you’re in the right spot. In this guide, we break down everything you need to know about sexism in the UK workplace, the laws that apply, your responsibilities as an employer, and the practical steps you can take to stay compliant and create an inclusive, successful team.

Let’s get into it - because tackling sexism early not only avoids legal headaches but can empower your business for long-term success.

What Exactly Is Sexism in the Workplace?

Sexism in the workplace refers to any behaviour, policy, or practice that treats someone less favourably because of their sex or gender. This might sound obvious, but sexism can take many forms - from blatant pay discrimination or unwanted sexual comments, to more subtle, systemic issues like promoting men over equally-qualified women, or assuming certain genders “don’t fit” certain roles.

Examples of workplace sexism include:

• Paying female employees less than men for the same work
• Making sexist jokes or demeaning remarks in meetings or emails
• Failing to promote a pregnant employee because of her pregnancy
• Refusing flexible work requests from women but approving them for men
• Overlooking candidates based on gender stereotypes (e.g. assuming men are better at manual jobs)

It’s important to remember that sexism can affect anyone - men, women, and non-binary individuals - and can occur between colleagues, managers and staff, or even from customers and clients.

Why Is Combating Sexism So Important for Businesses?

Apart from being just “the right thing to do,” rooting out sexism is essential for:

• Legal compliance - UK law strictly prohibits gender-based discrimination
• Building a positive workplace culture and employer reputation
• Retaining talented staff and avoiding the costs of staff turnover
• Boosting performance by ensuring everyone can thrive and contribute equally

Research shows that businesses that tackle sexism and promote equality outperform their peers, attract better candidates, and are less likely to face expensive legal disputes.

Which UK Laws Cover Sexism in the Workplace?

If you’re employing staff in the UK, several key laws directly address sexism, sexual harassment, and gender equality. The most important include:

• The Equality Act 2010: This is the main piece of legislation that protects employees from discrimination based on sex (as well as other “protected characteristics” like race, disability, age, etc.). It applies to recruitment, pay, promotions, training, dismissal, harassment and all areas of employment.
• Sex Discrimination Law: The Equality Act combined earlier sex discrimination laws into one clear framework, making it unlawful to treat workers less favourably because of their sex.
• Protection against Sexual Harassment: The Act also covers sexual harassment, meaning any unwanted conduct of a sexual nature that creates a hostile or intimidating environment.
• Equal Pay Act (now subsumed by the Equality Act): Employers must pay men and women equally for the same or equivalent work unless there’s a genuine (non-gender) reason for the difference.

Other laws, such as the Employment Rights Act 1996 and various UK employment laws, also provide important worker protections you’ll want to keep in mind.

What Are an Employer’s Legal Obligations Around Sexism?

Whether you employ one person or one hundred, UK law places clear legal duties on employers to prevent and respond to sexism in the workplace, including:

• Prevent Discrimination: You must not discriminate (directly or indirectly) against job applicants or employees based on sex or gender - in pay, hiring, firing, promotion, training, benefits and all other work-related matters.
• Address Harassment: Take reasonable steps to prevent sexual harassment and respond promptly to any complaints. This includes behaviour by colleagues, managers, customers, or even third parties who come into your workplace.
• Provide Equal Pay: Ensure men and women doing the same (or equivalent) work receive equal pay - unless the pay difference is justified for reasons unrelated to gender.
• Investigate Complaints: Respond quickly and fairly to sex discrimination or harassment complaints, following a clear, documented procedure. Avoid retaliation against people who make complaints (“victimisation” is also prohibited by law).
• Adjust for Family Circumstances: Don’t treat staff unfairly because of parental, pregnancy, or flexible-working requests - these are also protected under the Equality Act.

If you fail to meet these obligations, staff may bring their case to an employment tribunal, which can lead to hefty compensation payouts, fines, and severe damage to your reputation.

What Are the Different Types of Sexism Employers Need To Watch For?

Understanding how sexism manifests is the key to stopping it. The Equality Act recognises several main types:

Direct Discrimination

This is when a worker is treated less favourably specifically because of their sex - for example, rejecting a qualified candidate because they are a woman.

Indirect Discrimination

This happens when you have a rule, policy, or practice that applies to everyone, but disadvantages one gender unfairly. For example, requiring all staff to work late with no flexibility might adversely affect women who are statistically more likely to have primary caring responsibilities.

Harassment

Harassment is any unwanted conduct (including jokes, comments, texts, or behaviour) relating to sex or gender that creates an intimidating, hostile or offensive environment for the employee.

Victimisation

Victimisation is treated separately and occurs if someone is treated badly because they made (or supported) a complaint about sexism or discrimination.

Any of these could result in a costly legal claim, so it’s essential for employers to take them seriously and act quickly.

Proactively training your team, encouraging reporting, and setting a clear culture of respect goes a long way toward prevention.

What Practical Steps Can Employers Take To Prevent Sexism?

Complying with the law is non-negotiable, but the best employers go a step further by proactively fostering an open, fair and safe workplace.

Here’s your actionable employer checklist for preventing sexism at work:

• Build Strong Policies: Create a clear, written staff handbook with an equality and anti-harassment policy, plus a robust complaints procedure. Make sure every staff member knows these policies, and revisit them regularly. Find out more about staff handbooks here.
• Train Everyone: Provide regular training for all employees, managers and HR staff on what sexism looks like, bystander intervention, and how to report issues safely and discreetly.
• Promote Reporting: Encourage staff to speak up about inappropriate behaviour, and make it easy for them to make complaints confidentially without risk of backlash.
• Respond Quickly: Treat all allegations of sexism or harassment seriously. Investigate them fairly and act promptly to resolve issues - ideally following a consistent, predetermined procedure.
• Lead by Example: Managers and owners should model respectful, inclusive behaviour and be held to the highest standard.
• Audit and Adjust: Regularly review pay, promotion and hiring stats for gender bias. Don’t ignore patterns in complaints or team feedback, as these can indicate more systemic issues.

It’s sensible to get legal advice when creating your workplace policies and to have core company policies reviewed from time to time as regulations evolve.

What Should You Do If a Sexism Complaint Arises?

Handling complaints fairly is essential - not just for your legal protection, but to maintain staff trust and morale.

Here’s what to do if you receive a complaint about sexism in your business:

• Don’t ignore or dismiss the issue. Even if the claim seems minor or informal, investigate thoroughly.
• Follow your policy. Stick to your company's written complaints procedure, ensuring confidentiality for all parties involved.
• Document everything. Keep written records at every step - interviews, evidence, decisions and actions taken.
• Be fair and unbiased. Involve neutral HR representatives or external investigators if possible.
• Take action where needed. If sexism is found, act promptly: this might mean disciplinary action, changing processes, or providing further training.
• Avoid retaliation. Do not treat anyone differently because they raised (or helped address) a complaint.

Don’t forget-tribunal claims can be expensive and stressful, so resolving issues early is always in your best interests.

What Are the Risks of Not Addressing Sexism in the Workplace?

Ignoring sexism or failing to meet your legal obligations can lead to serious consequences, including:

• Tribunal claims and compensation payouts - Employees can bring discrimination cases (often with unlimited compensation totals in sex discrimination claims)
• Reputational damage - Tribunal decisions are public, which can impact your ability to hire or do business
• Fines and enforcement action - Especially if there is evidence of systemic failure to comply with equality laws
• Staff turnover and low morale - Poor culture leads to lost productivity and high recruitment costs

It’s simply not worth the risk - getting your legal foundations right will save you a world of hassle later.

Are There Other Key Employment Laws to Consider?

Sexism isn’t the only workplace risk for UK employers. You must also comply with laws around fair dismissal, redundancy, minimum wage and core employment rights for all employees.

It's also important to understand your obligations around other protected characteristics, like race, disability, age, religion, and sexual orientation. Learn more about your legal duties around these topics in our workplace discrimination guide.

Finally, make sure your employment contracts reflect your obligations to prevent discrimination and harassment. For help with contract drafting, check out our contract law guide for UK employers or get help drafting your employment contracts here.
