Lloyd’s of London have banned its workers from drinking during the working day following a discovery that half of disciplinary cases were relate to alcohol. The ban prevents the insurance market's 800 employees from drinking alcohol between 9am and 5pm, Monday to Friday. The policy was adopted after roughly half of grievance and disciplinary procedures in 2016 were found to be the result of consuming too much alcohol. The ban is included in the employee guide, which has been reviewed by HR. However, staff are less than impressed with the new rule, which will stop them from enjoying a drink at lunchtime. Lloyd's was founded in the 17th century, when it was a coffee house that served as a meeting point for sailors, merchants and ship owners to find out shipping news. A Lloyd’s spokesperson said, “Our employee guidance was recently updated and provided clarification on the Corporation’s position on drinking alcohol during the working day, which is prohibited.” The ban does not affect the brokers and underwriters from other firms who are based in the same building.
