Sainsbury’s fired a long-serving employee, Gary MacArthur, in March, according to reports. He worked at a store for 15 years before being dismissed for “gross misconduct.” The dismissal is linked to an allegation that he did not follow company guidance on “preventing incidents.” The reports describe an incident in which MacArthur tackled a suspected Champagne thief, described as “aggressive,” and also performed CPR on the store’s only security guard the same day. The accounts say the worker’s actions included confronting the suspected thief, while the security guard required emergency medical attention. The company position, as reported, focuses on compliance with its policies for handling incidents. The reports frame the case as a conflict between the employee’s intervention during an emergency and the company’s expectations regarding incident prevention procedures. No additional details about the thief’s identity, the security guard’s condition, or the exact internal findings are included in the provided summaries.
