Book excerpt: "Antitrust law has very rarely been used by workers to challenge anticompetitive employment practices. Yet recent empirical research shows that labor markets are highly concentrated, and that employers engage in practices that harm competition and suppress wages. These practices include no-poaching agreements, wage-fixing, mergers, covenants not to compete, and misclassification of gig workers as independent contractors. This failure of antitrust to challenge labor-market misbehavior is due to a range of other failures-intellectual, political, moral, and economic.
