Just weeks before President Donald Trump reportedly selected her to fill the new Supreme Court vacancy, Judge Amy Coney Barrett delivered a ruling that could help corporations evade long-standing laws requiring them to provide overtime pay to their workers.

That ruling was one of a number of cases in which Barrett helped corporate interests prevail over workers. Her highest-profile business-focused actions on the federal bench have limited the enforcement of age-discrimination laws, restricted federal agencies’ power to punish companies that mislead consumers, and reduced consumers’ rights against predatory debt collectors, according to a recent report from the Alliance for Justice.

Barrett’s August ruling in the overtime case is particularly significant: it comes as technology companies have been trying to use mandatory arbitration clauses to avoid better remunerating so-called gig workers. Those provisions often force worker disputes to be decided by private arbitrators handpicked by the companies, rather than in an impartial court of law.
