Bus assembly line workers at Proterra have decided to unionize, joining the United Steelworkers Local 675. Surprisingly, the firm's leadership has been incredibly supportive of unionization efforts. Following the union vote, Proterra voluntarily recognized the union. Many assumed that the firm's CEO, Ryan Popple, who previously worked as a finance executive at Tesla would take an antiunion stance. However, he views the union as a positive force- it has helped the firm align with environmental and labor advocacy groups which allows the firm to be more productive, overall.
