Thousands of Tesco office workers are being drafted in to stores to help serve customers on the retailer's busiest weekend of the year.

Around 3,300 Tesco head office staff - from buyers to board members - will be helping to pack bags, fill shelves and serve customers in what Tesco claims is the largest back-to-the-floor operation in the UK.

“Thousands of us will be rolling up our shirt sleeves and getting stuck in on the shop floor over the festive period,” said Tesco retail director David Potts who will also be heading out to stores.

“Christmas is the end product of months of preparation for us, but on the shop floor is where our customers see the results.”
