In the age of constant connectivity, what employees post online – whether during work hours or not – can have serious implications. For employers with staff members who use social media as a form of activism, as we have seen in the case of Gary Lineker and the BBC this week, the risk of reputational damage is higher than ever. What’s clear is that employers need to understand their rights, limits, and obligations when managing social media and employee misconduct online.
While employees have a right to a private life under Article 8 of the Human Rights Act 1998, this right is not absolute, especially where public posts conflict with an employer’s values or damage its reputation.
Even when using personal accounts, employees can face consequences if:
Employers are increasingly concerned about the reputational damage arising from social media activity, especially when posts go viral or attract media attention.
Key risks include:
In some cases, employers may even be found vicariously liable for employees’ online conduct if it occurs “in the course of employment” or in a work-related context.
Some employers, including NatWest Group, have taken measures as extreme as restricting access to messaging platforms like WhatsApp, Facebook Messenger, and Skype on company-issued devices in the UK to prevent employees from using them to communicate internally and to mitigate against these risks.
If online conduct breaches workplace policies or affects the employment relationship, disciplinary action may be appropriate.
Employers should:
Where the conduct amounts to gross misconduct, summary dismissal may be justified.
The following two examples demonstrate how online activity can have serious consequences, including escalation to an Employment Tribunal.
In the case of Crisp v Apple Retail (UK) Ltd [2011], an employee was fairly dismissed for making derogatory Facebook posts about Apple products, even though his profile was private. The Employment Tribunal found that Apple’s brand reputation justified the dismissal.
Similarly, in the case of Plant v API Microelectronics Ltd [2016] anemployee was dismissed for making a Facebook post criticising her employer, despite having 17 years’ service. The dismissal was upheld because the company had a clear social media policy, and the post breached it.
What steps can be taken to prevent matters like this from escalating to an Employment Tribunal?
