As Sainsbury’s faces an investor revolt on pay at its AGM today, there is one area of impact, however, that’s been rather glossed over, writes the FT’s Helen Thomas. Sainsbury’s directly-employed staff earn the living wage but its contractors and agency staff don’t. Accreditation gives three years to bring those workers up to the required pay levels. Sainsbury’s discloses very little about this workforce, which includes outsourced services such as cleaning and security. (The Financial Times £)

The Guardian’s Nils Pratley writes: “ShareAction has collected some high-profile supporters and deserves credit for ratcheting shopfloor pay up the boardroom agenda. The board of Sainsbury’s has been forced to pay attention. But a shareholder resolution at a single company is still an imperfect weapon for a scrap over low pay that really relates to sector-wide and national issues.” (The Guardian)
