"We know from our experience and international reports that even in the United States, workers are not allowed to unionize within Walmart," says Mike Abrahams, spokesperson for South African Commercial, Catering and Allied Workers Union. "We know from our experience internationally that where they've moved in, they've systematically eroded workers' rights and things like that. We don't want them here." He added that the unions are against the merger. Unfortunately for the unions, in 2011 Walmart purchased a majority stake in Massmart Holdings Limited, Africa's leading retailer of general merchandise, home equipment and supplies. Since Walmart is willing to work with unions to expand into foreign countries, why would they be so adamantly anti-union?
