(Mike Mozart)You may remember that this past spring, Walmart abruptly closed five stores in four different states to repair mysterious plumbing problems, leaving employees to find new jobs or maybe transfer to other nearby Walmarts. The closing was only ever meant to be temporary, though, and the stores have started to hire new and returning employees to staff the stores. The closing of five stores at once for the same ostensible reason was so unusual that conspiracy theories circulated: some were government-related and some were related to Walmart union-busting.
