Can I Get Fired for a Social Media Post? (Australian Law)

Can your boss sack you over something you posted on Facebook, Instagram, TikTok, or X? Yes — but only if there's a clear connection between your post and your employment. Your employer doesn't get to police your entire online life just because you work for them.

The Fair Work Commission has dealt with dozens of social media dismissal cases, and a clear pattern has emerged. Employers can take action when a post:

• Brings the employer into disrepute — damages the company's reputation in a meaningful way
• Reveals confidential information — trade secrets, client details, internal business matters
• Constitutes bullying or harassment of coworkers
• Breaches a lawful and reasonable social media policy that you were aware of

Outside of those situations, your employer's got a pretty weak hand. Posting a selfie on a Saturday night? Sharing a political opinion? Whingeing about the weather? None of that is grounds for dismissal.

Let's look at what's actually gotten people sacked — and the Commission upheld it.

In Little v Credit Corp Group Limited (2013), an employee was dismissed for posting derogatory comments about the company on Facebook. The FWC found the dismissal was fair because the posts were public, identified the employer, and damaged its reputation.

In O'Keefe v Williams Muir's Pty Ltd (2011), an employee posted offensive comments about their manager on Facebook. Even though the employee argued it was a private conversation, the FWC noted that Facebook posts can be shared and screenshotted — nothing on social media is truly private.

In Starr v Department of Human Services (2016), a public servant was sacked for anonymous political tweets. The Australian Public Service has stricter rules around political commentary, and the department successfully argued the tweets breached the APS Code of Conduct — even though they were posted anonymously.

The pattern is clear: if your post identifies your employer (or you're easily identifiable as their employee), and the content is offensive, confidential, or damaging — you're in the danger zone.

There are situations where sacking someone over social media activity is straight-up unlawful — regardless of what your employment contract or social media policy says.

Under the Fair Work Act 2009, your employer cannot take adverse action against you for:

• Exercising a workplace right — posting about your right to fair pay, safe conditions, or making a complaint (section 340)
• Union activity — posting about union membership, promoting union events, or encouraging others to join (section 346)
• Political opinions — the general protections provisions protect against discrimination based on political opinion (section 351)
• Making a complaint or inquiry — raising concerns about your employment, even publicly (section 341)

There's also a general principle that your employer's authority over you doesn't extend to every aspect of your private life. If you post something on a genuinely private account (locked down, not mentioning your employer, using a pseudonym), it's much harder for an employer to justify taking action.

The Fair Work Commission has consistently said there needs to be a sufficient connection between the social media activity and the employment relationship. A vague "we don't like it" isn't enough.

This is the phrase employers love to throw around, but it's got a specific meaning. "Disrepute" means actual damage to the employer's reputation — not just that they're embarrassed or annoyed.

For the FWC to accept a "disrepute" argument, the employer generally needs to show:

• The post was public or widely shared — a private message to a mate is different from a public rant with 10,000 views
• You were identifiable as an employee — either you mentioned the employer, or your profile makes it obvious where you work
• There was actual or potential reputational harm — did clients see it? Did it make the news? Did it contradict the employer's brand or values in a material way?
• The employer had a policy about this and you knew about it

A paramedic posting tasteless jokes about patients? That's disrepute. A retail worker posting "my job is boring" on their private Instagram story? That's just having a whinge, and any employer who sacks someone for that is asking for an unfair dismissal claim.

Context matters enormously. The more senior your role, the more public-facing your position, and the more sensitive your industry (healthcare, government, finance), the higher the standard you'll be held to.

What you do in your own time is generally your own business. The Fair Work Act doesn't give employers a roaming authority to monitor and punish everything employees do outside of work hours.

For out-of-hours conduct (including social media posts made on weekends or evenings) to justify dismissal, the employer needs to show a relevant connection to the employment. The classic test comes from Rose v Telstra (1998), which set out three situations where out-of-hours conduct can be relevant:

• The conduct is directly connected to the employment (e.g., a work event)
• The conduct damages the employer's interests
• The conduct is incompatible with the employee's duties

If your Saturday night post doesn't fit any of those categories, your employer is on shaky ground. The fact that they found your post doesn't mean they can act on it.

Before your employer can fairly sack you for social media conduct, they should also follow a proper process — which usually means investigating, giving you a chance to respond, and considering alternatives to dismissal. Skipping straight to termination over a single post (unless it's genuinely extreme) is often found to be unfair.

Look, the easiest way to avoid getting sacked over a social media post is to not post anything stupid about your employer. But beyond that common sense, here are some practical steps:

• Read your employer's social media policy. If they've got one, know what it says. It'll usually tell you what they consider a sackable offence
• Lock down your privacy settings. A private account with no mention of your employer gives you much more protection than a public one that lists them in your bio
• Don't use company devices for personal social media. If you're posting from a work phone or work laptop, your employer has a stronger claim to access
• Think before you vent. Even on a "private" account, screenshots exist. If you wouldn't say it in front of your boss, don't post it where it could end up on their desk
• Know the difference between venting and genuine misconduct. Saying "rough day at work" is fine. Posting client information, racist remarks, or threats against coworkers is a different thing entirely

If you've already been sacked or given a warning over a social media post and you reckon it's unfair, you've got 21 days from the date of dismissal to lodge an unfair dismissal application with the Fair Work Commission. Don't sit on it — that deadline is strict and extensions are rare.
