A health and safety dismissal can arise when an employee is dismissed because they raised a safety concern, refused to work in serious and imminent danger, or took steps to protect themselves or others. These cases are often urgent. The legal protection may apply from the first day of employment, and the deadline to begin a tribunal claim is usually short.
For employees, the central question is not simply whether a workplace was unsafe. It is whether health and safety action was the reason, or principal reason, for the dismissal. For employers, the key issue is whether a legitimate management decision can be clearly separated from any protected concern or safety activity.
When is a health and safety dismissal automatically unfair?
Under section 100 of the Employment Rights Act 1996, it can be automatically unfair to dismiss an employee for specified health and safety reasons. Unlike an ordinary unfair dismissal claim, an employee does not need two years’ continuous service to bring this type of claim.
Protection can apply where an employee was dismissed because they were a designated health and safety representative, carried out health and safety activities, or raised workplace conditions they reasonably believed were harmful or potentially harmful to health or safety.
It may also apply where an employee leaves, proposes to leave, or refuses to return to a workplace because they reasonably believe there is serious and imminent danger which they could not reasonably be expected to avert. The law also protects appropriate steps taken, or proposed, to protect the employee or other people from that danger.
The wording matters. A fear or concern does not have to be proved correct with hindsight. However, the employee must have held a reasonable belief in the relevant danger, and the facts will be assessed carefully. The nature of the role, available safety measures, guidance given by the employer and the employee’s knowledge at the time can all be relevant.
Health and safety concerns are not a licence to ignore every instruction
The law does not give an employee a blanket right to refuse any task they dislike or consider uncomfortable. A tribunal will look at the circumstances in context. Was there a genuine risk? Was it serious and imminent? Could the employee reasonably have avoided or addressed the danger? Did they explain their concern and give the employer an opportunity to respond?
For example, an employee who raises concerns about defective machinery, inadequate protective equipment, unsafe staffing levels or exposure to a hazardous substance may have a strong basis for protection. An employer that investigates promptly, pauses unsafe work where necessary and offers a safe alternative position is in a very different position from one that dismisses the employee without engaging with the concern.
The same applies where a worker refuses to attend a location. If the employer has taken reasonable measures to remove the risk, explained those measures and the employee continues to refuse without a sound basis, a disciplinary issue may arise. The outcome will depend on the facts, not on the label either party gives the dispute.
The real reason for dismissal is what matters
Employers rarely state that they are dismissing someone for raising a safety issue. A dismissal may instead be described as poor conduct, insubordination, poor performance, redundancy or a breakdown in working relationships. That does not end the legal analysis.
An employment tribunal can examine the timing of events, internal emails, meeting notes, witness evidence and the consistency of the employer’s explanation. If concerns were raised on Monday, the employee was suspended on Tuesday and dismissed shortly afterwards for an alleged issue that had previously been tolerated, the sequence may be significant.
Employees should retain evidence lawfully available to them, including copies of emails, messages, photographs, risk assessments, reports of incidents and notes of conversations. A clear contemporaneous record can be more persuasive than a later recollection. It is also sensible to set out concerns in writing, explain the risk identified and state what action is being requested.
Employers should avoid reacting defensively to a challenge. A manager who describes a safety complaint as being “difficult” or “not a team player” can create serious legal risk, particularly where the employee later faces disciplinary action. Concerns should be investigated on their merits, with the employee protected from retaliation while the facts are reviewed.
Dismissal is not the only legal risk
A person does not always have to be dismissed to have a potential claim. Workers, as well as employees, may be protected from being subjected to a detriment for taking certain health and safety action. A detriment can include reduced hours, removal from duties, denial of training, threats, an unjustified disciplinary warning or being treated less favourably after raising concerns.
Employment status matters. Employees have the potential protection of automatic unfair dismissal under section 100, while workers may have different statutory rights. Senior individuals, consultants and those engaged through intermediaries may need particularly careful advice, as the written contract is not always decisive.
Health and safety disputes can overlap with other legal rights. If the information raised is in the public interest and meets the legal test, it may amount to whistleblowing. If an employee is treated unfavourably because of a disability, pregnancy or another protected characteristic, discrimination law may also be relevant. A properly structured case identifies each possible claim early rather than assuming there is only one route.
What employees should do after a health and safety dismissal
Act promptly, even where you hope the employer will reverse its decision. Ask for the dismissal reason in writing if it has not been clearly provided. Consider whether there is an internal appeal and submit it within the stated deadline. An appeal can correct an unfair outcome, but it should not be allowed to distract from tribunal time limits.
Most employment tribunal claims must be started within three months less one day of the effective date of termination. Before issuing a claim, you will usually need to notify Acas through early conciliation. The process can pause the limitation period, but the calculation is technical and it is unwise to leave it until the final days.
There is also a potentially valuable urgent remedy. In some automatic unfair dismissal cases, including health and safety cases, an employee can apply for interim relief. This application must normally be made within seven days of dismissal. If successful, it can preserve pay or employment-related income pending the final hearing. The time limit is exceptionally short, so early legal advice is essential.
Possible remedies include reinstatement, re-engagement, a basic award and compensation for financial losses. In a successful section 100 claim, the usual statutory cap on the compensatory award does not apply. That said, compensation is evidence-based. An employee should keep records of job-search efforts, lost earnings, pension loss and benefits lost following dismissal.
How employers can manage safety concerns without increasing exposure
The safest response to a concern is not always the quickest operational response. Employers should assess the reported risk, listen to the employee’s account and document the steps taken. Where there is a potential immediate danger, stop or modify the work while an appropriate assessment is completed.
A fair process will often involve speaking to relevant managers and witnesses, reviewing risk assessments and training records, considering whether control measures are working, and giving the employee a meaningful response. If the complaint is unfounded, explain why. If it reveals a weakness, correct it and communicate the change.
Where a separate conduct or performance concern exists, deal with it carefully and independently. Do not allow safety complaints to be folded into vague allegations of attitude or refusal to cooperate. A disciplinary process should identify the allegation, disclose the evidence, give the employee a genuine opportunity to respond and consider alternatives to dismissal. Decision-makers should be able to show that the protected health and safety activity played no part in the outcome.
Policies are useful only when managers understand and follow them. Clear reporting routes, regular risk assessments, training, consultation with safety representatives and consistent investigation procedures reduce the prospect of harm as well as the prospect of litigation.
A dismissal following a health and safety concern can affect income, reputation and workplace confidence quickly. Whether you are deciding how to challenge a dismissal or how to respond to a difficult safety issue, obtaining clear advice early can protect your position and help focus attention on a lawful, practical resolution.
