Walmart has reportedly closed a smattering of its stores across the country citing “plumbing problems”. The mega-retailer’s media cohorts are reporting the mystery but won’t say that the closures coincide with stores which have been hardest hit by labor unrest. It turns out, Walmart has opted to close its doors where employees have most successfully organized “Fight For Fifteen” actions. By suddenly closing the stores Walmart preempted further organizing and punished the upstarts by laying off all the store’s employees with only a few hours notice. Walmart claims the plumbing problems will take a half year to fix. I think what remains of Walmart’s workforce has been given a wonderful opportunity to retaliate in kind. What of these plumbing problems? Are Walmart’s other stores showing signs of plumbing problems too? Might a larger wave of plumbing problems be induced? I think Walmart’s union-busting advisors have loosed a weapon that will prove more consequential for Walmart than its wage-slave victims. Foisted on their own petard, I believe is the expression. Petard in this case is substituted by toilette. Walmart customers can even get in on the act, err, investigation, for free. Come to Walmart empty handed, find a bag of cement in the hardware aisle, proceed to the public bathroom, flush it presto plumbing problem. Citizen plumbers can turn this plumbing mystery into a plumbing thriller.
