And in other business news, Wal-Mart has announced plans to close a store in Canada where workers were seeking to turn the store into the first unionized Wal-Mart in North America. The world’s largest retailer claimed the store closure was necessary because demands from union negotiators would make it impossible for the store to be profitable. It is the first Wal-Mart to close for economic reasons. For years Wal-Mart has vigorously fought unionizing efforts. Five years ago, a group of Wal-Mart butchers voted to unionize. The company responded by announcing that it would start stocking prepackaged beef and that there would no longer be a need for butchers.
