You’ve probably seen it on Facebook: a friend letting it all out in a post about their frustrations at work, usually followed by an outpouring of support from friends in the comments section. Sometimes the author of the post will name the employer, or even call them names. But is publicly criticising your boss legal? Could it get the employee dismissed?

This article will look specifically at media posted outside the course of employment, and made on a staff member’s personal device. In particular, we’ll look at the consequences of employees publicly criticising their employer. 

Can Employees Be Dismissed For Posting Negative Comments About Their Workplace?

Employees can be dismissed in certain circumstances. In the UK, the right to freedom of speech can found in Article 10 of the Human Rights Act.

This right has to be balanced with impartiality that certain employees must show, in particular government employees. As well as this, employees must not bring their employer into disrepute or violate any hate speech laws.

The key takeaway here is that there is a right to express yourself, but there are limitations to this right where it breaches other laws.

Private Sector Employees

In the 2012 Linfox case, a staff member working for a private company (Linfox, a transport company) complained on his Facebook about two of his managers. He made negative comments about them, and was dismissed as a result. 

The employee successfully argued this was unfair dismissal, with Fair Work ruling the employee should be paid compensation for lost wages and get his job back. 

Some key issues that were taken into consideration by Fair Work were:

  • The staff member believed his Facebook was set to a ‘friends only’ privacy setting and could only be seen by a limited number of people
  • The employee did not fully understand how Facebook works (in 2020, this will be harder to argue!)
  • There was no workplace social media policy 
  • His posts were seen as within his right to free speech
  • He had worked at Linfox for over 20 years and did not have previous problematic behaviour

Can An Employee Be Dismissed For Any Other Types Of Posts?

Yes, they can. Employees can and have been dismissed for posts that don’t criticise their employer, but are otherwise offensive. 

Some posts may be violent in their nature and directed at a person, or incite hatred against a person or group because of their race, ethnicity, gender, sexual orientation, religion, disability, or other factor. 

So, can you fire someone even if it’s not political or about work, but because they’ve demonstrated that they’re a bit of an unsavoury character? Understandably, even if the post is not connected to work, the person is, and this can bring your business into disrepute.

In 2015, a supervisor who worked at Meriton posted sexist and violent comments on Clementine Ford’s social media account. Once Meriton was made aware of this, they promptly dismissed the employee, and informed the target of the sexist attacks that they did not condone the employee’s behavior. This is an example of a dismissal based on social media posts bringing an employer into disrepute. 

In some cases, a post may violate the law. There is a ton of legislation aimed at making hate speech illegal. For example, there’s the Public Order Act 1986.

Why It’s Important To Have A Social Media Policy

Social media should be broader than just Facebook and Twitter. Having a policy will firstly make clear what you mean by social media, and then clarify what conduct is acceptable. 

It is important to sensitively balance the rights of your employees to use social media to express themselves with the need to protect your business’ reputation. This will be different for private companies than it will be for public servants. 

In Summary

Employers may have a right to dismiss staff who make posts on social media, even if anonymously, and even if it’s done on their own device outside of work hours. 

Some common reasons to dismiss employees based on social media use include breaching a social media policy or code of conduct, breaking a law through inciting hate speech, bringing an employer into disrepute or risking impartiality.

We strongly recommend you seek legal advice before deciding to terminate a staff member’s employment.
