About 300 jobs could be under threat at two Wincanton sites in the north of England. This follows Sainsbury's decision to consolidate operations supporting its convenience store business to a depot at Sherburn-in-Elmet, North Yorkshire. The two affected depots are at Maltby, South Yorkshire, and Skelton in Teesside. A Wincanton spokesman says it is looking to redeploy staff to other sites in the region. However, the firm is talking to customers about potential use for the two sites.
