This guidance is for employees in the UK. A social media post does not, by itself, prove that you were fit to work or dishonest about being ill. What matters is the context: your condition, the activity, your job duties, timing, medical advice and the workplace rules that apply. If your manager raises the post, respond calmly, find out the specific concern and follow the sickness-absence process.
What to do first
- Keep the context. Save a copy of the post, its date and relevant surrounding context. Do not alter or delete material to change the record after your employer has raised a concern.
- Check the workplace rules. Read the sickness-reporting and absence policy, social-media policy, disciplinary rules and any contact plan agreed for your absence. Acas recommends that employers set out social-media expectations in relevant policies and make unacceptable behaviour clear (Acas social-media guidance, last updated 22 May 2025).
- Ask what the concern is. You could reply: “I understand you saw the post. Could you tell me what specific concern or policy you want to discuss? I’m happy to explain the context and follow the agreed sickness-absence process.” Adapt this to the facts; do not assume the post can never be relevant.
- Keep health communication proportionate. Explain what is needed to address work-related capacity or comply with the absence process, without volunteering unnecessary medical detail. Agree reasonable contact while you are off sick; GOV.UK says employers and employees should agree how to stay in touch and how much contact is reasonable (GOV.UK fit-note guidance for employers and line managers).
- If the matter becomes formal, engage with the process. Ask for the allegation and the material being relied on, take time to prepare a factual response, and ask whether you may bring a companion. Consider support from a union representative, Acas or an independent employment adviser if the consequences could be serious.
Can you get in trouble for posting while off sick?
Possibly, depending on the circumstances—but a post alone does not establish misconduct or settle whether you were fit for work. An employer may ask about activity that appears inconsistent with what you reported, but the activity needs to be considered in context. Being able to do one thing does not necessarily mean you could perform all the duties of your particular job.
For example, a photograph of someone outdoors or socialising may not show how they felt at other times, what restrictions their condition caused, or whether their job requires different physical or mental demands. The post’s date, circumstances and any relevant medical advice may also matter. The official guidance does not prescribe a particular outcome for a social-media post; no general outcome or probability can be inferred from the fact that a manager saw one.
What a fit note does—and does not—tell your employer
In the UK, you can usually self-certify if you are off sick for seven calendar days or less. If you are off for more than seven days in a row, you generally need a fit note. A fit note may say you are “not fit for work” or “may be fit for work” (GOV.UK: Taking sick leave).
#1 Best Overall
A fit note concerns your health and fitness for work; it is not a ruling about every activity outside work. If it says “may be fit for work,” government guidance describes discussing possible workplace changes. Employers should also consider the Equality Act and reasonable adjustments when managing sickness absence and a return to work (GOV.UK fit-note guidance for employers and line managers). Whether adjustments or other legal protections apply depends on your circumstances.
If your employer starts a disciplinary investigation
An investigation is not the same as a finding that you did something wrong. Acas’s Code of Practice says employers should carry out necessary investigations without unreasonable delay to establish the facts. It also describes giving the employee an opportunity to explain their case, communicating the decision in writing and providing an appeal route (Acas Code of Practice on disciplinary and grievance procedures, published 11 March 2015).

- Ask for the precise allegation, the policy said to be involved and the evidence the employer is considering.
- Prepare a factual account of the post’s context, the date and how your health affected your ability to do your job.
- Ask whether you have the right to be accompanied. Eligible workers have a statutory right to a companion at disciplinary hearings when the conditions in the Acas Code apply; the Code also provides for a companion at eligible appeal hearings.
- If you think the decision is wrong or unjust, use the employer’s appeal route and set out your grounds in writing.
Acas says its codes set minimum fairness standards and that employment tribunals take them into account in relevant cases. That does not mean every procedural shortcoming determines a case or guarantees a particular result.
Does your manager have a right to look at a personal post?
Do not assume that a manager is barred from seeing content that is publicly available. Government guidance on workplace monitoring says employers should clearly explain the extent of monitoring in the staff handbook or contract (GOV.UK workplace monitoring guidance). That guidance concerns workplace monitoring generally; it does not establish that every view of a public personal post is unlawful or prohibited.
