Can I Be Dismissed for a Social Media Post?

Yes. A social media post is conduct, and your employer can dismiss you for it where the post is serious enough, breaks a clear policy or harms the business, and a fair process is followed. Your employer must still act reasonably, and some posts are shielded by law.

A post is treated as conduct

Section 98 of the Employment Rights Act 1996 lists conduct as a potentially fair reason for dismissal. A post made outside working hours on a personal account can still count as conduct connected to your job. It is more likely to count where you name your employer, identify colleagues or customers, share confidential information, or post abusive or discriminatory content about people you work with.

Posting from home does not move the post outside your employment. What matters is the link between the content and your work.

Policy and reputational harm

Your employer's social media policy tells you what is expected. A clear policy that warns that certain posts may be treated as gross misconduct makes a dismissal easier to justify. If there is no policy, or the policy is vague, your employer must show that you knew, or should have known, that the post was unacceptable.

Ask for the policy that applied on the date of the post, not a later version.

Your employer may argue that your post damaged its reputation. A tribunal will look for evidence. Relevant factors include whether the post named the employer, how many people saw it, whether customers or the press reacted, and how quickly you removed it. A post seen by a handful of friends carries less weight than one shared widely with the employer tagged.

Privacy and freedom of expression

Article 8 of the European Convention on Human Rights, the right to respect for private life, and Article 10, freedom of expression, both form part of UK law through the Human Rights Act 1998. Tribunals take them into account when a dismissal concerns your private life. The balance often turns on who could see the post. A public post, or one visible to colleagues, carries a lower expectation of privacy. Privacy settings help, but contacts can screenshot and share a post.

If your post expressed a religious or philosophical belief, section 10 of the Equality Act 2010 may apply. Dismissing you because of the belief is discrimination. An employer can still act on the manner in which a belief was expressed, where the response is proportionate.

The whistleblowing exception

If your post disclosed wrongdoing in the public interest, such as a danger to health and safety, a criminal offence or a breach of a legal obligation, it may be a whistleblowing disclosure under section 43B of the Employment Rights Act 1996. Since 6 April 2026, sexual harassment is also a qualifying category. Dismissal for a qualifying whistleblowing disclosure is automatically unfair under section 103A of the same Act, with no qualifying service needed.

Disclosures made to the public, including on social media, are covered only under strict conditions in that Act. Raising the concern with your employer or a prescribed body first is usually required. A post that is a personal complaint about your treatment is not whistleblowing.

A fair process still applies

Your employer must investigate, tell you in writing what is alleged, show you the post it relies on, hold a hearing, allow you to be accompanied and offer an appeal, as the ACAS Code of Practice on Disciplinary and Grievance Procedures requires. Your length of service, clean record, whether you deleted the post and whether you apologised are all relevant to whether dismissal was a reasonable response.

An example

A hospital receptionist with four years of service posted on her public account about a patient's behaviour in the waiting room, naming the patient. The trust's social media policy banned sharing any patient information. Naming the patient is a confidentiality breach, and dismissal may be within the range of reasonable responses even as a first offence. Had she complained about a long shift without naming anyone, dismissal would be much harder for the trust to justify.

What to do next

1. Take screenshots of the post, its privacy setting and any reactions before anything is deleted.
2. Ask for the social media policy and the evidence your employer relies on.
3. Write down when you posted, who could see it, and when you removed it.
4. Prepare for the hearing, including any explanation, context and apology.
5. If you are dismissed, appeal within the deadline. Acas states that time limits for employment tribunal claims increased from 3 months to 6 months on 1 October 2026. The 3 month limit may still apply to problems that started before 1 October 2026. Check your deadline early and seek advice. Ordinary unfair dismissal needs two years of service for dismissals before 1 January 2027, and six months from that date (planned, subject to Parliament).

Before your disciplinary hearing, write down what you posted, when and why, and seek advice.
