first question will probably be "What is this doing on HN". It has to do with the trend of many US companies, fire people to increase profits: The Bentonville, Arkansas-based retailer’s workforce at its namesake and Sam’s Club warehouse chains in the U.S. fell by about 120,000 employees between 2008 and Jan. 31, according to a securities filing on March 26.
