Asda offers its staff a 10% discount card after three months service. The card can be used in any Asda store in the UK and in any global Walmart, Asda's parent company. Using the card, Asda's 175,000 staff save over £60 million a year.

When Asda launched an online voluntary benefits scheme in 2010, it also included discounts on its own services, such as insurance, access to opticians, flower delivery and car breakdown cover.

Angela Woodward, reward manager at Asda, says: "By offering staff discounts throughout the business, they become engaged and can also provide insight into the company brand."
