Workplace Discrimination: Laws, Duties & Prevention

If you’re running a business or thinking about hiring employees in the UK, understanding workplace discrimination is not just good practice-it’s a legal must-have. Discrimination at work isn’t just about avoiding awkward moments or bad press; it’s about meeting really clear legal duties that apply to every employer, regardless of size or industry.

Whether you’re a startup founder ready to grow your team, or an established business trying to keep your workplace fair and compliant, getting this right matters for your people and your business’s future. In this guide, we’ll break down what workplace discrimination actually means under UK law, your core responsibilities as an employer, and practical steps to help you prevent issues before they start.

Let’s take the confusion out of discrimination law and set your business up for legal-and ethical-success.

What Is Employment Discrimination In The UK?

Employment discrimination is when someone is treated less favourably in the workplace because of a specific “protected characteristic”. In plain terms-if someone is hired, fired, promoted, paid, or treated differently at work because of a personal trait protected by law, that’s discrimination. Discrimination at work is illegal in the UK under the Equality Act 2010.

This law doesn’t just apply to employees; it covers job applicants, trainees, contract workers, and even former employees. So from writing a job ad right through to redundancy or dismissal, your duty as an employer is clear: treat everyone fairly, and never base decisions on protected characteristics.

What Are the Protected Characteristics Under UK Law?

There are nine protected characteristics. Discrimination on any of these grounds is unlawful:

• Age
• Disability
• Gender reassignment
• Marriage and civil partnership
• Pregnancy and maternity
• Race (including colour, nationality, ethnic or national origin)
• Religion or belief
• Sex
• Sexual orientation

If a staff member, applicant, or even a customer believes they’ve been treated unfairly due to one of these traits, it could lead to a legal claim-no matter how small your business is.

Types of Discrimination in the Workplace

Discrimination doesn’t always look the same, and UK law recognises several types you need to be aware of:

• Direct Discrimination: Treating someone less favourably specifically because of a protected characteristic. For example, not promoting a woman to a senior role because she is pregnant.
• Indirect Discrimination: When a rule, policy, or practice that applies to everyone disadvantages people with a particular protected characteristic. For example, demanding all staff work Sundays could disadvantage certain religious groups.
• Discrimination by Association: Treating someone unfairly because they associate with another person who has a protected characteristic (e.g. penalising an employee because their spouse is disabled).
• Discrimination by Perception: Discriminating against someone because you believe they have a protected characteristic-even if that’s not actually the case.
• Harassment: Unwanted conduct related to a protected characteristic which violates someone’s dignity or creates an intimidating, hostile, degrading, humiliating or offensive environment.
• Victimisation: Treating someone unfairly because they’ve complained about discrimination or helped someone else do so.

It’s important to remember that discrimination at work can be obvious, but sometimes it might be subtle or even unintentional. What matters is the effect on the individual-not the employer’s intent.

For deeper insight, our article on difference between an employee and a contractor explains how different work statuses are treated in law (which can intersect with discrimination considerations).

Where Does the Law Apply? (And When Should You Worry?)

Discrimination law covers much more than just day-to-day working life. Here’s where you need to be alert:

• Hiring and Recruitment: Job adverts, selection criteria, interviews, and offers must all be discrimination-free.
• Pay and Benefits: Equal pay for equal work is a legal right-regardless of a protected characteristic.
• Terms and Conditions: All employees must have the same access to opportunities, training, and promotions.
• Redundancy and Dismissal: Decisions about who stays or goes must not be based on a protected characteristic.

Even one-off comments, internal policies, or the way flexible working requests are handled can fall under scrutiny if they disadvantage someone because of a protected trait. Discrimination law applies from the first point of contact (such as a job application) to the very last (such as after employment ends).

Examples of Unlawful Discrimination at Work

Let’s bring this to life with a few scenarios you might not realise are discrimination in the workplace:

• Rejecting a qualified candidate because their name “sounds foreign”.
• Failing to promote a staff member because she’s recently returned from maternity leave.
• Setting a uniform policy that doesn’t reasonably accommodate religious dress requirements.
• Implementing an attendance bonus, knowing that some disabled employees cannot meet “perfect attendance” standards.
• Ignoring repeated age-related jokes aimed at an employee nearing retirement age.
• Refusing to make adjustments for an employee with dyslexia who requests assistive technology.

These are all examples of unlawful discrimination. Sometimes, what looks like “company culture” or “business as usual” actually risks breaching the law.

Reasonable Adjustments for Disability: What’s Required?

If you employ (or are hiring) someone with a disability, the Equality Act places a specific duty on you to make reasonable adjustments. This means taking steps to remove barriers so that disabled people can work, apply for jobs, or enjoy the same rights as others.

“Reasonable” will depend on your business size, budget, resources, and the practicality of any change. But common examples include:

• Changing working hours or shift patterns
• Adapting recruitment processes or interviews
• Providing special equipment or support
• Altering physical premises to allow access
• Adjusting job roles or reallocating duties

Failing to make reasonable adjustments is a form of disability discrimination, so it’s essential to assess requests promptly and fairly.

Your Duties As An Employer: Preventing Discrimination

The legal duty to prevent discrimination is active, not passive. In other words, you must take reasonable steps to make sure discrimination and harassment don’t happen-and, if a problem arises, to act promptly and effectively.

Practical Steps For Prevention

• Have a clear policy: Create and communicate an equal opportunities or anti-discrimination policy.
• Training: Train managers and staff on what discrimination looks like and how to report it.
• Act on complaints: Set up easy ways for staff to raise concerns and make sure all complaints are taken seriously.
• Lead by example: Senior leadership must model non-discriminatory behaviour-company culture starts at the top.
• Monitor decisions: Regularly check recruitment, pay, promotion, and redundancy decisions for any bias or trends.

As an employer, you can also be held vicariously liable for discriminatory actions committed by your employees unless you can show you took all possible steps to prevent it. This means it’s crucial to have clear, accessible policies (and evidence of staff training) in place.

Employee Rights: What If Discrimination Happens?

If an employee feels they’ve experienced unlawful discrimination at work, they can:

• Raise the issue informally or formally within the organisation (grievance procedure)
• Seek advice from Acas or a trade union
• Lodge a formal complaint with the business
• Bring a claim to an Employment Tribunal

It’s possible for claims to be made not just against the business, but also against individuals (e.g. managers) who participated in discrimination.

Remedies can include compensation for loss of earnings, injury to feelings, recommendations for changes in the workplace, and even reinstatement.

How Can You Prove Discrimination At Work in the UK?

Proving discrimination is about showing that less favourable treatment was because of a protected characteristic. Evidence may include:

• Written communications (emails, messages)
• Comparisons with how others are treated
• Patterns or discrepancies in promotional or pay decisions
• Witness statements

Businesses should keep comprehensive and consistent records to help resolve disputes (and show that fair processes were followed).

Common Pitfalls: Don’t Let These Trip Up Your Business

Let’s be honest-some of the most common ways discrimination in the workplace occurs are also the easiest to overlook, especially for busy SMEs:

• Relying on “word of mouth” or casual chats for hiring-risking unconscious bias
• Not advertising roles fairly or widely (e.g., only to existing networks)
• Failing to update policies to cover all protected characteristics
• Assuming flexible working requests can be declined without explanation
• Neglecting to record key decisions or keep meeting notes
• Ignoring “banter” that makes someone feel isolated or uncomfortable

The law expects you to be proactive-have a paper trail, consistent policies, and make sure your managers are trained to spot issues early.

Key Steps To Prevent Workplace Discrimination

• Draft or update an equal opportunities policy, and share it with all staff
• Deliver regular equality and anti-discrimination training (yes, even for small teams!)
• Audit job ads, contracts, pay reviews, and appraisals to spot any potential bias
• Ensure all reasonable adjustments requests (especially for disability) are swiftly assessed
• Set up a fair complaints and grievance process-make it easy to use
• Keep clear and complete records of all employment decisions
• Review your procedures and workplace culture regularly-don’t set and forget

Adopting these best practices is not just about legal compliance; it supports a healthier, happier (and more productive) workplace.
