Every few decades one company stands head and shoulders above the rest in the contest for the country’s “worst labor law violator.”

In the 1960s and 1970s, the textile giant J.P. Stevens most deserved the title; the New York Times wrote that the settlement eventually reached between the company and its union marked “the end of one of the ugliest episodes in recent labor history: a 17-year war during which Stevens repeatedly harassed or fired union activists.” In the 1990s, Caterpillar’s dispute with the auto workers union generated several hundred allegations of unlawful management practices. In the early twenty-first century, Walmart repeatedly violated its pro-union workers’ rights, leading the National Labor Relations Board (NLRB) to issue a sweeping “consolidated” charge against the company — essentially a nationwide “cease and desist” order — in January 2014. In the past few years, Amazon’s unlawful efforts to crush unions have attracted widespread media coverage.
