Worlds collided this week when the Retail, Wholesale and Department Store Union released a statement trashing pop star Kelly Clarkson. In case you haven’t been keeping up, Clarkson accused a worker at the Art of Play toy store in Brooklyn of condescending treatment when she inquired about purchasing a mechanical singing bird, which the clerk claimed wasn’t for sale despite a visible $15,000 price tag. RWDSU criticized Clarkson for putting a random retail worker on blast to her millions of followers. Even an American idol isn’t safe from the ire of organized labor.
