Lloyd’s passholders who show signs of being under the influence of alcohol will be barred from entering the market’s premises during working hours, under new rules announced last week.

The ban extends a move two years ago to prohibit employees drinking alcohol while at work.

Lloyd’s says the ban also applies to illegal drugs, and anyone breaching it risks having their pass confiscated.

The market has also set up a 24-hour bullying and harassment hotline for whistleblowers and victims to report incidents.

Lloyd’s has vowed to take tough action after a Bloomberg report described the atmosphere as one of “near-persistent harassment”, based on accounts from several female executives.

“Further actions… include establishing a market-wide access point for reporting inappropriate behaviour, undertaking a market-wide culture survey, a comprehensive review of policies and practices across the Lloyd’s market and provision of preventative training,” Lloyd’s says.
