The American Federation of Teachers (AFT), the second largest teachers’ union in the country, passed a resolution in support of the Green New Deal at its biennial convention at the end of July. The Green New Deal, federal legislation introduced in early 2019, would create a living-wage job for anyone who wants one and implement 100% clean and renewable energy by 2030. The endorsement is huge news for both Green New Deal advocates and the AFL-CIO, the largest federation of unions in the United States. The AFT’s endorsement could be a sign of environmental activists’ growing power, and it sends a message to the AFL-CIO that it, too, has an opportunity to get on board with the Green New Deal. But working people’s conditions are changing rapidly, and with nearly half of all workers in the country without a job, the leaders of the AFL-CIO and its member unions may choose to knuckle down on what they perceive to be bread-and-butter issues, instead of fighting more broadly and boldly beyond immediate workplace concerns.
