Despite a crowded Democratic primary field and a flurry of high stakes primary races scheduled for February, major labor unions have have been unusually cautious to endorse any candidates, taking their time to vet over 20 contenders. But on Monday, United Electrical, Radio, and Machine Workers of America (UE), a 35,000-worker industrial union, announced it is throwing its support behind Vermont Senator Bernie Sanders.

The endorsement arrives just one day after Sanders rallied with striking AT&T workers in downtown Louisville, Kentucky, and less than a week after Sanders released his plan for Workplace Democracy, which pledges to double union membership in the United States by the end of his first term in 2025 with the expansion workers’ rights to unionize, strike, and bargain.
