Strategic Organizing Center

The Strategic Organizing Center (SOC), formerly known as the Change to Win Federation (CtWF), is a North American national trade union center originally formed in 2005 as an alternative to the AFL-CIO. The coalition is associated with strong advocacy of the organizing model. The coalition currently consists of Service Employees International Union (SEIU), the United Farm Workers (UFW), and the Communications Workers of America (CWA), the former and latter of which are affiliated with both the SOC and the AFL-CIO. Michael Zucker is currently listed as the Executive Director of the organization since 2020.

The SOC also includes SOC Investment Group, a shareholder engagement arm of the SOC that challenges management of large, publicly traded companies targeted by the SOC's campaigns.
