On Thursday, the Change to Win unions released twenty resolutions they’re submitting for votes at the AFL-CIO’s convention at the end of this month. Echoing the dissidents’ May platform, these amendments would commit the Federation to rebate dues to unions prioritizing new organizing, empower it to demand accountability from unions which aren’t and facilitate strategic mergers, and strengthen the power of the most populous unions with the AFL-CIO’s decision-making structure. They would commit the federation to aggressively promote internal diversity, international solidarity, and responsible budgeting. They would commit the federation to foster cooperation and the maintenance of bargaining standards within industries and solidarity across the movement in fighting for retirement security, universal healthcare, and global justice. And in defiance of the threats Sweeney’s issued should the dissidents split off, one of their resolutions would open central labor councils to the participation of non-AFL-CIO unions.

Given that Sweeney has the votes locked down for re-election (though a few are speculating he could still be pressured into bowing out), the debate and voting over these resolutions is likely to be the greatest flashpoint for controversy at the federation’s most contentious convention in a decade. And what happens to these resolutions will be crucial to determining whether the dissidents continue to pursue their agenda for change through the federation or whether they make a break.

As the Change to Win unions consider their next move, they’ve been joined last week by the Carpenters, who formally affiliated with Change to Win four years after themselves splitting off from the AFL-CIO over similar concerns. The Change to Win dissidents have played a key role in keeping the pressure on to stop Sweeney from forcing the Carpenters out of participation in the federation’s Building and Construction Trades Department, and the Carpenters were players in the New Unity Partnership as well. Their affiliation is no surprise, but it does help to further swell the new coalition and puts front and center the model of a union which has experienced success since breaking away from the AFL-CIO. The real coup for the dissidents would be pulling in the National Education Association (NEA).

All of this friction, though certainly tense, has the potential to transform a movement and a set of organizations sorely in need of it, and turn around the decline in American union membership which has steadily pulled the efficacy of the broader left down with it. But don’t take it from me – take it from the prestigious anti-union law firm Morgan Lewis:

If the Coalition’s members follow through on their threats to disaffiliate from the Federation later this year, employers can expect an increased interest in union organizing. This could be especially true for the nation’s largest non-union employers. For employers with existing unionized workforces, this means increased pressure to execute some form of neutrality and card-check recognition agreement. For employers with unions from both competing factions at their facilities, competition for better wages, benefits and other terms and conditions of employment is likely…the raiding between AFL and CIO constituent unions that occurred prior to 1955 will now play out between Coalition’s members and those remaining loyal to the Federation. The last several years have seen a significant increase in the amount of collaboration between U.S.-based unions and their international counterparts. That collaboration could increase significantly. Finally, more union mergers should be forthcoming.
