A spokesman for Tesco said: "It’s wrong to say there are job losses – all the people at the three sites will be offered alternative roles at other Tesco sites. Plus, we are creating 2000 jobs at Reading and Dagenham.
"We will now have a period of consultation with colleagues and their representatives. We will do everything we can to support them at this time."
"We are opening two new distribution centres in Reading and Dagenham to create 1900 jobs in total."
