A dedicated employee at Sainsbury’s, who was dismissed for intervening in a theft shortly after aiding a colleague in distress, expressed deep disappointment over the company’s decision. Gary MacArthur, a shop assistant with 15 years of service, was let go for confronting a thief attempting to steal high-end champagne and causing a disturbance by throwing glass bottles. Earlier that day, MacArthur had performed CPR on a coworker who had suffered a stroke.
The incident took place at the store in West Wickham, South London, where the thief exploited a security gap to carry out the theft. MacArthur, aware of the situation, took action to safeguard the store and its patrons.
Upon recalling the events, MacArthur recounted how he had responded to his colleague’s medical emergency before being alerted to the thief’s presence. Recognizing the repeat offender, he confronted the individual and escorted him out of the store, discovering a bag suspected of containing stolen items nearby.
Despite returning the goods to the stockroom, the thief reentered the store and started breaking bottles, posing a threat to the staff. MacArthur, along with a customer, restrained the thief until law enforcement arrived. However, three months later, MacArthur was terminated for gross misconduct for not adhering to Sainsbury’s guidelines on handling such situations.
In a letter to MacArthur, the company emphasized that he should have acted solely as a visual deterrent and not engaged physically with the thief. MacArthur expressed his deep attachment to his job and the impact of the dismissal on his life, as work colleagues were his main social circle, aside from his pets.
Despite his attempts to appeal the decision, the outcome remained unchanged. Earlier, in August 2025, MacArthur had received a written warning for a similar incident involving a thief. This case mirrors the dismissal of another long-term employee, Sean Egan, from Morrisons, highlighting the challenges faced by retail workers in dealing with theft and aggression.
In response to such incidents, a Sainsbury’s spokesperson emphasized the company’s commitment to enhancing security measures and collaborating with authorities to combat crime. The company stressed the importance of prioritizing safety and preventing situations from escalating, rather than expecting employees to confront offenders directly.
