The PRO Act is emerging as the left’s answer to a classic political tension. Stephanie Keith/Getty Images Representative Jamaal Bowman, a vocal supporter of the PRO Act Tuesday night, the Protecting the Right to Organize Act passed the House by 225–205 votes. If it passes the Senate and becomes law, it will peel back over half a century of anti-union policies, including core provisions of the Taft-Hartley Act of 1947. It would override state-level right-to-work protections—the darlings of the Koch brothers machine—and create harsher penalties for employers who interfere with employees’ organizing efforts. But in myriad ways, the act might also do something unexpected: set the stage for sweeping climate policy.
