At its annual general meeting (AGM) on Wednesday, retailer Sports Direct will face questions over the use of zero hour contracts for part time staff...Responsible investment campaign ShareAction will use the company’s AGM, set to be held at Shirebrook on September 10, to raise awareness of the issue and ask Sports Direct about the practice...Catherine Howarth, chief executive of ShareAction, said, “Investors should be asking Sports Direct about the risks of continuing to operate with zero hour contracts. Employers who routinely depend on these arrangements could soon find themselves on the wrong side of the law."  Howarth added, “At a time when millions of working people in the UK are becoming pension savers for the first time, ShareAction want to see the UK’s major pension providers using their shareholder power to demand decent working practices in companies like Sports Direct and an end to wasteful, multi-million pound bonuses for executive directors.”
