NATIONAL REPORT — As the number of retail staff who stay home increases, retailers are looking for ways to keep people on the store floor. Loblaw has asked head office people, including executives, to help out in stores as staffing becomes more difficult. According to the National Post, about 400 corporate staff are now contributing by doing shifts at the stores. At Walmart Canada, dozens of head-office staff have stepped up to devote time to serving customers in the stores.
