Understanding Employer Vicarious Liability Beyond the Workplace

The following is an abridgement of an article originally published by HSE Network.

Understanding Vicarious Liability

According to HSE Network, employers face legal exposure through vicarious liability, a principle where organizations can be held responsible for the wrongful acts of their employees if the actions occur during the course of employment. The article notes that establishing liability involves a "relationship test" to confirm an authentic connection between the employer and perpetrator, and a "close connection test" to determine if the act is sufficiently linked to the employee's authorized duties.

Case Law and Precedents

HSE Network reports that liability can extend to customer-facing incidents, workplace accidents, data mishandling, and harassment, even if an employee acts against specific protocols. The publication cites a case involving a supermarket chain where the employer was held vicariously liable for a serious wrongful act committed by an employee. Conversely, in a 2022 case involving a cement and lime company, the court ruled the employer was not liable for an employee's practical joke that caused injury, deeming it outside the scope of employment.

In a 2025 case involving a pub chain, a customer sustained injuries while being restrained by third-party door staff. The judge initially found the company liable, but the decision was reversed on appeal because the contract was deemed "for services" rather than "of service," highlighting the importance of clear contractual definitions.

Off-Duty Exposure and Risk Management

The article highlights that organizations may underestimate exposure from off-duty conduct, particularly at social events. In Chief Constable of Lincolnshire Police v Stubbs, the employer was held accountable for harassment between two off-duty officers during a social event because it was attended almost exclusively by employees at a closed premises, which the court deemed to be in the course of employment.

To navigate liability issues, HSE Network advises employers to review conduct policies for off-site behavior, audit contractor arrangements against current case law, train line managers on off-duty responsibilities, and review insurance coverage to ensure it reflects the scope of exposure.
