Unfair Dismissal (UK / Australia)

A statutory claim that an employee's termination was unjust, unreasonable, or carried out without a fair process, available to eligible employees in the UK (under the Employment Rights Act 1996) and Australia (under the Fair Work Act 2009).

What Is Unfair Dismissal?

Key Takeaways

  • Unfair dismissal is a statutory right that protects employees from being fired without a valid reason or without a fair procedure. It exists separately from wrongful dismissal (which is a contract claim about notice).
  • In the UK, employees need at least two years of continuous service to claim ordinary unfair dismissal. In Australia, the qualifying period is six months (or twelve months for small businesses with fewer than 15 employees).
  • UK law defines five potentially fair reasons for dismissal: conduct, capability, redundancy, statutory illegality, and some other substantial reason (SOSR). Any reason outside these five is automatically unfair.
  • Australia's Fair Work Act 2009 asks whether the dismissal was "harsh, unjust, or unreasonable" based on factors including the reason, whether the employee was notified, whether they had an opportunity to respond, and whether warnings were given.
  • Both systems require employers to follow a fair process. Even if the reason for dismissal is valid, an unfair procedure can make the termination unlawful.

Unfair dismissal protects employees from arbitrary or procedurally flawed terminations. The core principle is simple: you can't fire someone without a good reason and a fair process. Unlike wrongful dismissal (which only looks at whether the employer gave proper notice), unfair dismissal examines why the employee was fired and how the employer went about it. In the UK, this protection comes from the Employment Rights Act 1996. In Australia, it comes from the Fair Work Act 2009. Both systems recognize that employees invest years of their lives in a job, and losing that job without justification causes serious harm. The legal frameworks differ in their details, but the underlying principle is the same. Did the employer have a genuine reason? Did they investigate properly? Did they give the employee a chance to respond? Was the punishment proportionate? If the answer to any of these questions is no, the dismissal may be unfair.

Unfair Dismissal in the UK

The UK's unfair dismissal regime is one of the most established employment protection systems in the world, running since the Industrial Relations Act 1971.

Eligibility requirements

To bring an ordinary unfair dismissal claim, a UK employee must have at least two years of continuous service with the employer (since April 2012). There are exceptions: dismissals for certain reasons are automatically unfair regardless of service length. These include dismissals related to pregnancy or maternity leave, whistleblowing under the Public Interest Disclosure Act 1998, trade union membership or activities, asserting a statutory right, and health and safety activities. Employees on fixed-term contracts that aren't renewed can also claim unfair dismissal if they meet the service requirement.

Potentially fair reasons

The employer must show the dismissal was for one of five potentially fair reasons: conduct (the employee did something wrong), capability (the employee can't do the job due to skill or health), redundancy (the role is no longer needed), statutory illegality (continued employment would break the law, such as a driver losing their license), or some other substantial reason, known as SOSR (a catch-all for business reorganizations, personality clashes, and other situations that don't fit the first four categories). Having a fair reason is necessary but not sufficient. The employer must also show they acted reasonably in treating that reason as sufficient grounds for dismissal.

The range of reasonable responses test

UK tribunals don't ask whether they would have fired the employee. They ask whether the employer's decision fell within the "range of reasonable responses" that a reasonable employer could have made. This gives employers some latitude. Two reasonable employers might reach different conclusions on the same facts. As long as the decision isn't outside the range of responses that any reasonable employer could have reached, it won't be unfair. This test applies to both the decision to dismiss and the procedure followed.

Unfair Dismissal in Australia

Australia's unfair dismissal protections under the Fair Work Act 2009 are administered by the Fair Work Commission (FWC), an independent national workplace relations tribunal.

Eligibility requirements

To claim unfair dismissal in Australia, the employee must have completed the minimum employment period: six months for employers with 15 or more employees, or twelve months for small business employers (fewer than 15 employees). The employee must also be covered by the national workplace relations system (which covers most private sector employees). Additionally, the employee must earn below the high-income threshold (AUD 167,500 as of July 2023) or be covered by a modern award or enterprise agreement. Employees earning above this threshold without award coverage can't access the unfair dismissal system but may have common law breach of contract claims.

The harsh, unjust, or unreasonable test

The Fair Work Act uses three overlapping concepts. A dismissal is harsh if the consequences are disproportionate to the seriousness of the conduct (for example, firing a 20-year employee for a first minor offense). It's unjust if the employee didn't actually do what they were accused of, or if the employer's allegations weren't substantiated. It's unreasonable if the employer failed to follow a proper process: no investigation, no opportunity to respond, no genuine consideration of alternatives to dismissal. The FWC considers the employee's service length, any prior warnings, and the size and resources of the employer when applying this test.

The Small Business Fair Dismissal Code

Small businesses (fewer than 15 employees) that follow the Small Business Fair Dismissal Code receive protection from unfair dismissal claims. The Code sets out a simplified process: for serious misconduct, immediate dismissal is acceptable. For other reasons, the employer must give the employee a warning and a reasonable chance to fix the problem. The employer must genuinely believe the conduct occurred and must have reasonable grounds for that belief. If the employer follows the Code, the FWC must find the dismissal was fair. This is a significant safeguard for small businesses that lack formal HR departments.

What Counts as a Fair Dismissal Procedure

Both the UK and Australia place heavy weight on whether the employer followed a fair process. Even a legitimate reason for dismissal can become unfair if the process was flawed.

Investigation

The employer must conduct a reasonable investigation into the alleged misconduct or performance issue before making a decision. This means gathering evidence, interviewing witnesses, reviewing documents, and forming a genuine belief based on reasonable grounds. The investigation doesn't need to be police-quality, but it must be proportionate to the allegation. Firing someone based on a single anonymous complaint without further investigation is unlikely to survive scrutiny in either jurisdiction.

Right to respond

The employee must be told the allegations against them and given a meaningful opportunity to respond before the decision is made. In the UK, this means a disciplinary meeting where the employee can hear the evidence, present their side, and bring a companion (a colleague or trade union representative). In Australia, the Fair Work Act explicitly requires that the employee be notified of the reason and given an opportunity to respond. Decisions made before the employee responds are almost always unfair.

Right to appeal

In the UK, the Acas Code of Practice on Disciplinary and Grievance Procedures requires employers to offer a right of appeal after a dismissal decision. Failure to offer an appeal can increase compensation by up to 25%. The appeal should be heard by a different, more senior manager than the one who made the original decision. In Australia, while there's no equivalent code, failing to offer an appeal is a factor the FWC considers when assessing whether the process was reasonable.

Automatically Unfair Reasons for Dismissal

Certain reasons for dismissal are automatically unfair regardless of the employer's process or the employee's length of service. No qualifying period applies.

  • Pregnancy, childbirth, or maternity/paternity/adoption/shared parental leave (UK and Australia).
  • Whistleblowing or making a protected disclosure about workplace wrongdoing (UK: Public Interest Disclosure Act 1998; Australia: Fair Work Act Part 3-1).
  • Trade union membership, activities, or industrial action within protected periods (both jurisdictions).
  • Asserting a statutory employment right, such as requesting a written statement of terms or raising minimum wage concerns (UK).
  • Temporary absence due to illness or injury (Australia, within protected periods under the Fair Work Act).
  • Filing a complaint or participating in proceedings under workplace health and safety legislation (both jurisdictions).
  • Exercising workplace rights, including making a complaint or inquiry about employment conditions (Australia: general protections under Part 3-1).
  • Jury service (UK: automatically unfair; Australia: covered under general protections).

Remedies for Unfair Dismissal

Both jurisdictions offer reinstatement and compensation as remedies, though their practical application differs significantly.

UK remedies

The UK offers three remedies: reinstatement (return to the same job on the same terms), re-engagement (return to a different but comparable role), and compensation. Compensation has two components: a basic award (calculated like statutory redundancy pay based on age, service, and weekly pay up to GBP 643 per week in 2024) and a compensatory award (capped at the lower of GBP 115,115 or 52 weeks' gross pay). In practice, reinstatement is ordered in fewer than 1% of successful claims. Most employees receive compensation only. The median award at UK employment tribunals for unfair dismissal is approximately GBP 13,000.

Australia remedies

The Fair Work Act positions reinstatement as the primary remedy and instructs the FWC to consider it before compensation. In practice, reinstatement is ordered more frequently than in the UK but still represents a minority of outcomes. When compensation is awarded instead, it's capped at 26 weeks' pay (based on the employee's actual remuneration). The FWC also deducts earnings from other employment during the notice period and considers any mitigation efforts. There's no separate basic award component like in the UK. The FWC can also order the employer to pay a specified amount for lost remuneration during the period between dismissal and the decision.

Frequently Asked Questions

Can I claim unfair dismissal if I was made redundant?

Redundancy is a potentially fair reason for dismissal in both the UK and Australia, but the employer must follow a fair redundancy process. In the UK, this means using fair selection criteria, consulting with affected employees, and considering alternative employment within the organization. If the employer selects employees for redundancy based on discriminatory criteria or doesn't consult properly, the dismissal can be unfair even though the redundancy itself was genuine. In Australia, genuine redundancy is a complete defense to an unfair dismissal claim, but the employer must show the role was truly no longer needed and that they complied with any consultation obligations under an applicable award or enterprise agreement.

What if I resigned instead of being fired?

If you resigned because the employer made your working conditions intolerable, you may have a constructive dismissal claim. In the UK, constructive unfair dismissal requires showing the employer committed a fundamental breach of contract and you resigned in response without undue delay. In Australia, the Fair Work Act recognizes forced resignation (where the employee had no real choice but to resign due to the employer's conduct) as a form of dismissal eligible for unfair dismissal protection. The burden of proof is on the employee to show the resignation wasn't truly voluntary.

Does unfair dismissal apply to contractors and casual workers?

Generally, no. Unfair dismissal protections apply to employees, not independent contractors. In Australia, casual employees can claim unfair dismissal only if they have been employed on a regular and systematic basis for the qualifying period and had a reasonable expectation of continuing employment. In the UK, only employees (not workers or self-employed contractors) can bring unfair dismissal claims. The distinction between employee, worker, and self-employed status is a frequent source of litigation in both countries.

Can my employer fire me during probation?

In the UK, employees within their first two years of service generally can't claim ordinary unfair dismissal, so a probationary dismissal typically doesn't create unfair dismissal liability (unless it's for an automatically unfair reason). In Australia, the minimum employment period (six months, or twelve months for small businesses) serves a similar function. Dismissals during this period are generally excluded from the unfair dismissal system, though the employee may still have protections under general protections provisions if the dismissal was for a prohibited reason.

How much does it cost to bring an unfair dismissal claim?

In the UK, there are currently no fees to lodge an employment tribunal claim (fees were abolished in 2017 after the Supreme Court ruled them unlawful). Legal representation costs vary, but many employees use free advice from Acas, Citizens Advice, or trade unions. In Australia, the FWC charges a filing fee (AUD 83.30 as of 2023-24), which can be waived for financial hardship. Many Australian employees represent themselves in FWC proceedings, especially during the conciliation stage. If the matter proceeds to a hearing, legal costs can range from AUD 5,000 to AUD 30,000+.
