Yes — an Australian employer can lawfully dismiss an employee for social media posts, but only when specific legal thresholds are met. The Fair Work Commission (FWC) has held that social media conduct outside working hours can form a valid reason for dismissal when it damages the employer’s reputation, breaches a clear social media policy, or constitutes bullying, harassment, or serious misconduct toward colleagues.

However, the FWC has also found dismissals unfair where employers lacked a social media policy, failed to follow procedural fairness, or overreacted to posts with minimal workplace connection. The maximum unfair dismissal compensation from 1 July 2026 is $95,050 (half the $190,100 high income threshold). Employees have 21 days to lodge a claim with the FWC. For employers with 15+ employees, the minimum employment period is 6 months; for small businesses under 15, it is 12 months under the Small Business Fair Dismissal Code.

When Can Social Media Posts Justify Dismissal?

The Fair Work Act 2009 requires a valid reason for dismissal related to the employee’s conduct or capacity (s.387(a)). The FWC has identified situations where social media posts can meet this threshold:

• Damage to employer reputation: Posts that defame the employer, disclose confidential information, or bring the business into disrepute.
• Workplace bullying or harassment: Posts that target, intimidate, or humiliate colleagues — including after-hours conduct that damages workplace relationships.
• Breach of a clear social media policy: Posts that violate specific rules the employee was aware of and had agreed to follow.
• Connection to employment: Posts that reference the workplace, clients, products, or colleagues in a way that could harm the employment relationship.

The key test is whether a reasonable employer would consider the posts sufficient reason for dismissal. Posts on a personal account about non-work topics carry less weight than posts directed at the employer. However, private posts can be actionable if they constitute bullying of co-workers. Employers should draw on established performance management frameworks rather than reacting impulsively.

Key Fair Work Commission Decisions on Social Media Dismissal

The FWC’s approach has evolved. Key decisions highlight important principles:

Linfox Australia Pty Ltd v Stutsel [2012] FWAFB 7097: An employee posted racially and sexually offensive comments about two managers on Facebook. The FWC found the dismissal unfair because the employer had no social media policy and the employee believed his posts were private. While the Full Bench found a valid reason existed, procedural failures meant the dismissal was still harsh.

O’Keefe v Williams Muir’s Pty Ltd [2011] FWAFB 2423: An employee posted offensive comments about a manager after hours. The FWC found the dismissal unfair because there was no social media policy and the employer had not investigated the connection to the workplace.

These cases established the core principle: a valid reason alone is not enough. The employer must also have a clear policy, investigate properly, and follow procedural fairness at every stage. For broader coverage, see our earlier article on social media and unfair dismissal.

Steps Employers Must Take Before Dismissing

Before dismissing an employee for a social media post, you must follow a structured process. Skipping steps is the most common reason dismissals are overturned:

1. Review your social media policy: Confirm the employee was aware of it and the post breaches specific provisions.
2. Gather evidence: Screenshot the post, note the date and audience. Document any actual damage caused.
3. Investigate: Interview the employee and check whether the post was taken out of context.
4. Issue a show cause letter: Give the employee a reasonable opportunity to respond — at least 24 to 48 hours. Access general employment document templates including show cause letters from our document hub.
5. Consider alternatives: Assess whether a formal warning or performance management plan is more proportionate than dismissal.
6. Document your decision: Only proceed if the conduct justifies termination, and record your reasoning in writing.

For small businesses under 15 employees, the Small Business Fair Dismissal Code provides a checklist. Summary dismissal for serious misconduct is permitted but requires sufficient investigation. Following HR best practice standards will protect your business.

What Your Social Media Policy Must Include

A robust social media policy is the foundation of any lawful dismissal for social media misconduct. Without one, the FWC is likely to find the dismissal unfair. Your policy should cover rules on identifying the employer or colleagues on personal accounts, prohibition of bullying and harassment, confidentiality of company information, consequences of breaches up to and including dismissal, and after-hours conduct affecting the workplace. Communicate it to all employees with signed acknowledgement and review annually.

Serious Misconduct vs Performance Issues

Not every problematic post warrants dismissal. The Fair Work Act 2009 defines serious misconduct as wilful or deliberate conduct causing imminent risk to health, safety, or the business reputation. Social media posts involving bullying, threats, or sexual harassment may meet this threshold. Less serious posts are better addressed through formal warnings and progressive performance management — the FWC has found disproportionate responses make dismissals harsh, unjust, or unreasonable under s.387.

General Protections and Adverse Action Risks

Dismissing an employee for social media posts can trigger a general protections claim under s.351 of the Fair Work Act if the post relates to a protected attribute like political opinion, religion, or union activity. General protections compensation is uncapped — unlike the $95,050 unfair dismissal cap (half the $190,100 high income threshold from 1 July 2026) — so the financial risk is higher. Seek legal advice before acting if the post touches on any protected attribute.
