M&S stores director Helen Milford said: “Our teams really step up over the festive period to help make Christmas special for our customers, including working extra hours so we can keep our store doors open for longer.
“It’s a busy time for retail so giving our colleagues Boxing Day off is a small thank you for their hard work delivering a remarkable Christmas for our customers.”
The daily rewards consist of a combination of freebies and personalised offers such as 20 percent off Christmas prosecco and 15 percent off the knitwear.
