Four months into Israel’s brutal assault on Gaza that has killed over twenty-eight thousand Palestinians, the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) — the US labor federation whose member unions represent 12.5 million workers — issued a statement on February 8 urging a negotiated cease-fire to end the violence.

The move came after over two hundred US unions and labor bodies — including national unions like the United Electrical Workers (UE), American Postal Workers Union (APWU), United Auto Workers (UAW), International Union of Painters and Allied Trades (IUPAT), National Nurses United (NNU), Service Employees International Union (SEIU), National Education Association (NEA), Communications Workers of America (CWA), and American Federation of Teachers (AFT) — had already made cease-fire calls of their own. Many unions, especially at the local level, have also expressed solidarity with the Palestinian liberation movement.

With the backing of the AFL-CIO and the nation’s two largest unions (NEA and SEIU), support for a cease-fire is now the mainstream position of the American labor movement. Given US labor officialdom’s history of providing substantial political and material aid to the state of Israel — along with its frequent partnering with US empire (which I examine in my forthcoming book, Blue Collar Empire) — this is a remarkable development highlighting the power of rank-and-file organizing to push union leaders on critical issues, and signaling the possibility of building a more internationalist labor movement.
