When you terminate an employee's contract without a fair reason, it's an unfair dismissal. You may also hear it called an unlawful dismissal...

Unfair redundancy is another term you might come across—but the official employment law terminology is unfair dismissal.

An employment tribunal (some businesses mistakenly call this an unfair dismissal tribunal) will find a dismissal unreasonable if you dismissed an employee for one of the following:

  • A reason that was automatically unfair.
  • Without following a fair dismissal procedure.

However, this employment law topic is much more complex than a brief explanation can summarise. And it’s important for your business to have a good understanding of how to approach unfair dismissal in the workplace.

If you don’t, you may end up having to face a costly employment tribunal process.

So, we’re here to take you through the ins and outs of unfair dismissal. Then you’ll know what you should avoid doing as an employer.

Unfair dismissal law—essential information

Okay, so UK law explains that this issue is about dismissing a member of staff without a fair reason.

But, of course, you must remember there are fair reasons to let employees go. Five of them, in fact—these are:

  1. If there’s an act of misconduct, which can result in instant dismissal.
  2. A lack of capability for the role.
  3. Due to redundancy reasons.
  4. If a statutory duty arises. For example, if you have a delivery driver who receives a permanent ban.
  5. The other fair reason is some other substantial reason (SOSR)

There are no grounds for unfair dismissal—you must have a reason to remove an employee from your business. The above examples are all legitimate.

When is it an automatic unfair dismissal?

Employees need two years of service to bring a claim for unfair dismissal.

And the dismissal becomes automatically unfair if you violate one or more of your employee’s statutory employment rights.

When an unfair dismissal in the UK isn’t automatically unfair, your recruit needs two years’ service with you (minus one week).

They must also be an employee, rather than a worker or self-employed.

Firing someone for any of the following are automatically unfair reasons for dismissal. So, these are unfair dismissal examples:

  • Membership with a trade union.
  • Employee exposed wrongdoing in your workplace (whistleblowing).
  • Maternity/paternity leave.
  • Adoption leave.
  • Shared parental leave.
  • They refuse to give up a right under the Working Time Regulations 1998—such as the right to a rest break.
  • They tried to enforce their right to receive the national minimum wage.

There are plenty of other reasons, too. These are just the most common. If your recruit has a spent criminal conviction they haven’t declared, you can dismiss them until they reach two years’ service.

After that, you guessed it—automatically unfair.

Getting rid of someone because he or she had to do jury service is automatically unfair, too.

Unfair dismissal compensation for employees

If an employment tribunal decides that you dismissed someone for a reason that was automatically unfair, you’ll owe your former employee compensation. This is also the case for unfair dismissals.

Maximum compensation in these cases is usually one-year’s pay, up to a limit of £86,444 (whichever is lower), with a basic award added on.

If you fired somebody for a health & safety reason, or because they blew the whistle, the compensation could be a lot higher.

Again—this is one of those reasons where your staff don’t need to have worked for you for two years.

Unfair dismissal redundancy during probation period

To dismiss someone during a probationary period quickly, have a term in your contract that allows you to do this.

This is because, from time to time, a new hire won’t work out and you’ll need to dismiss someone while they’re on probation.

An employee must have worked for you for at least two years, as we mentioned earlier, to make an unfair dismissal claim.

So for an employee with you for a certain period, with unfair dismissal under 2 years it’s 103 weeks of service for them to make a claim for unfair dismissal.

But of course, your staff has entitlements to all contractual rights from day one.

As we also covered earlier, discriminatory or most automatically unfair dismissals don’t need a qualifying period.

It’s your job as the employer to make sure you go through your disciplinary and dismissal procedures. For conduct and performance purposes.

Unfair dismissal rights for your employees

To protect your business, and to ensure staff receive fair treatment, you should always make sure you:

  • Provide staff copies of all procedures and policies.
  • Make notes of all actions when an event could lead to an employment tribunal.
  • Keep copies of all messages.

Do these things and you can prove you made your member of staff aware of all company rules.

But before you dismiss anyone, you should look to take steps to try and solve the issue. For example—with a disciplinary procedure. The steps for this include:

  • Have an informal talk with the employee in question—after this, you may notice an improvement in their conduct.
  • You should first hold an investigation, which can include an investigation meeting to establish the facts (although that isn’t essential to do so). If following an investigation you feel the allegation has scope, you can then move to a disciplinary procedure.
  • At this point, you would have a disciplinary hearing and allow them to bring a union representative, or colleague, if they wish.
  • Make a decision based off the investigation.
  • Allow for the employee to appeal the decision.

The eventual sanction, such as a verbal, written or final warning, should come straight after the disciplinary.

If you issue the employee a warning at this stage, and their conduct doesn’t improve, you’ll have to implement a separate disciplinary procedure to establish if a more serious sanction is necessary.

The final step is you can dismiss the employee after they fail to improve. This protects you against a claim for unfair dismissal.

However, you should be aware the process doesn’t always follow the same pattern of warnings and then a dismissal.

If the employee’s conduct is very serious, you can provide a final warning at the first instance—or even dismiss them.

But it’s important to treat your employees consistently throughout the process.

Disciplinary appeal hearing for unfair dismissal

You should make sure your appeals procedure for employees to challenge decisions is clear.

You might find the appeal process lets you move forward without an employment tribunal.

If not, your employee has three months, minus one day, to begin the process of an unfair dismissal claim from the rejection of their appeal.

Losing an employment tribunal hearing can result in a heavy fine—it may be as high as £86,444.

There’s a basic award added on as well. Currently, this is £15,750.

As such, it’s essential you take steps to provide a genuine reason for letting a member of staff go.

Maintain records of their behaviour if you have concerns so that you can back up your claims at a later date.

Other types of dismissal

Finally, there are other types of dismissal your business must be aware of.

The first is constructive dismissal, which is where an employer manipulates an employee’s role to force them to resign.

An example here is if the business provides a staff member with an impossible workload, so they fail to meet KPIs or leave due to stress.

Another type is wrongful dismissal—this involves an employer breaching an employee’s contract of employment.

So as you can see here, the difference between wrongful and unfair dismissal is the former is about a contractual breach. That’s all about contract law.

For wrongful dismissal, a common example is an employee receiving the wrong amount of notice.
