Supermarket chain Asda , subsidiary of US retailer Wal-Mart and one of Britain's largest employers, has revealed plans for a new scheme to make new grandparents entitled to seven days leave when a baby is born. A pioneer in employee motivation and flexible work practises, Asda already allows parents to stop working for short times during the school holidays and instituted a half-day off policy on children's first day of school. It was encouraged to extend this practise when it was revealed that nearly 14,000 older workers are forced to dip into their annual holiday in order to assist their families when a grandchild is born.
