Can Small Businesses Face Unfair Dismissal Claims?

Many small business owners in England and Wales assume that being a small employer shields them from employment tribunal claims. In reality, once a person is an employee, even a small business can face claims for unfair dismissal, automatic unfair dismissal, discrimination, and related legal challenges if legal rights are breached. This article explains how unfair dismissal law applies to small businesses, the key legal tests, qualifying periods, procedural requirements, potential risks, and practical guidance for both employers and employees.

What Is Unfair Dismissal?

An unfair dismissal occurs when an employer terminates an employee's contract without a fair reason or fails to follow a fair procedure before dismissing. Under current law, the main fair reasons include:

• Conduct (including gross misconduct);
• Capability or qualifications;
• Redundancy;
• Statutory illegality (e.g. loss of a required licence);
• Some other substantial reason (SOSR).

For a standard unfair dismissal claim, the employee normally must have completed a minimum qualifying period of continuous service. At present, this is two years. Once the Employment Rights Act reforms take effect, this qualifying period will reduce to six months, extending unfair dismissal protection to more employees - including those in small businesses - from 1 January 2027.

If a dismissal is for an automatically unfair reason (such as whistleblowing or asserting a statutory right), the qualifying period does not apply.

Employees who cannot bring standard unfair dismissal claims may still bring claims for automatic unfair dismissal, constructive dismissal, discrimination, or wrongful dismissal depending on the circumstances.

Small Employer Status Does Not Prevent Claims

From a legal standpoint, there is no separate exemption for small businesses simply because of size. If an organisation employs people under contracts of employment, those individuals are likely to be considered employees with rights under the Employment Rights Act 1996 and the Equality Act 2010 once they meet statutory tests.

This means that whether you are a micro‑business employing a handful of staff or a medium‑sized enterprise, the same basic legal framework for unfair dismissal applies. Small businesses must therefore understand and comply with procedural and substantive rules when dismissing employees.

Qualifying Periods and Small Businesses

Current Law

Under current law, the employee must normally have two years' continuous service before they can claim unfair dismissal at an employment tribunal, except in cases of automatic unfair dismissal such as discrimination or whistleblowing.

This has historically given small employers some flexibility in managing dismissals of very short‑service staff, provided there was no unlawful reason. However, this does not remove the need for fairness and lawful grounds.

Changes Ahead

The UK government's Employment Rights Bill will reduce the qualifying period for standard unfair dismissal claims to six months. This reform responds to ongoing political negotiation but, as currently anticipated, will take effect from 1 January 2027.

For small businesses, this change materially increases exposure to unfair dismissal claims because more employees will be eligible to bring claims sooner in their employment. In practical terms, businesses that rely on informal probationary processes or casual dismissal may need to adopt more robust documentation and fair procedures to defend potential claims.

Automatically Unfair Dismissal Claims

Even if the qualifying period has not been met, an employee may still bring an automatically unfair dismissal claim if their dismissal was for specific prohibited reasons, such as:

• Whistleblowing;
• Health and safety complaints;
• Exercising a statutory right (e.g. National Minimum Wage requests);
• Family or maternity rights;
• Trade union activities.

Automatically unfair dismissal claims do not depend on service length, meaning small employers can be exposed to tribunal claims from day one of employment if they dismiss for prohibited reasons.

Procedural Fairness and Risk

Unfair dismissal claims focus not only on whether there was a valid reason for dismissal but also on whether the employer followed a fair process. Tribunals will look at things such as:

• Whether the employee was informed of concerns and given an opportunity to respond;
• Whether any investigation was thorough and documented;
• Whether the employer followed its own disciplinary or dismissal procedures; and
• Whether the Acas Code of Practice on Disciplinary and Grievance Procedures was adhered to, where relevant.

Failure to follow fair procedures can lead to a tribunal finding unfair dismissal, even if the underlying reason might otherwise have been justifiable.

Small Business Practical Risks

Increased Exposure

With the qualifying period reducing, small employers will face additional exposure to unfair dismissal claims sooner in the employment relationship. This can be particularly significant where:

• Small businesses lack formal HR policies;
• Employers rely on informal processes or “common sense” dismissal decisions;
• There is limited documentation of performance or conduct concerns.

Costs and Tribunals

Tribunals can award compensation for unfair dismissal, including a basic award and a compensatory award. Under proposed reforms, the cap on compensatory awards will be fully removed for standard unfair dismissal claims, potentially increasing financial risk, particularly for small employers without adequate insurance or reserves.

Discrimination and Other Claims

Small employers must also guard against discrimination claims under the Equality Act 2010. Discriminatory dismissals can be challenged without a qualifying period and attract separate liability.

Steps Small Businesses Should Take

Establish Clear Policies

Small businesses should develop written policies on disciplinary processes, performance management, grievance handling, and dismissal procedures. This provides clarity and helps to demonstrate fairness if a claim is brought.

Document Decisions

Maintain accurate records of performance reviews, warnings, investigations, meetings, and communications. Documentation strengthens an employer's position in defending claims.

Provide Training

Owners and managers should understand basic employment law principles and fair procedures. Investing in training can reduce the risk of procedural errors that tribunals often scrutinise.

Seek Early Advice

Before dismissing an employee, particularly where the case is complex, obtain advice from employment law solicitors or advisors. Early guidance can help avoid missteps that lead to tribunal claims.

Common Questions

Can a small business employer be sued for unfair dismissal?
Yes. Small businesses have the same legal obligations as larger employers when dismissing employees. Employees with sufficient qualifying service - or those claiming automatic unfair dismissal - can bring claims to an employment tribunal.

Does size affect the legal test for fairness?
No. Tribunals apply the same fairness and procedural standards regardless of employer size.

Can claims arise before qualifying service?
Yes. Dismissals for automatically unfair reasons (such as discrimination or whistleblowing) are not subject to length‑of‑service requirements.

What are the risks of poor procedures?
Failing to follow fair procedures can make an otherwise lawful dismissal unfair and expose the business to compensation claims.

Key Takeaways

Small businesses in England and Wales can and do face unfair dismissal claims. Although traditional qualifying periods offered some protection, upcoming reforms will expand rights to claim after six months' service, and claims for automatically unfair dismissal require no qualifying period at all. Small employers must therefore understand their legal obligations when managing performance, conduct, redundancy, disciplinary matters and dismissals, and ensure that they follow fair and transparent procedures. Clear policies, good documentation, and early legal or HR advice are vital to mitigate the risk of tribunal claims and associated costs.
