The National Fast Food Workers’ Union (NFFWU) was established by the Service Employees International Union (SEIU) shortly to supersede the Fast Food Workers Committee as the lead organizing entity for the unionization arm of the national union’s “Fight for $15” campaign. The National Fast Food Workers’ Union is the latest in a series of organizations created for the purpose of the unionization of franchise restaurant workers.
According to National Fast Food Workers’ Union 2018 annual report with the U.S. Department of Labor, the Service Employees International Union provided 87.1 percent of NFFWU’s revenue—over $6.1 million—in “direct support” and “strike support.” 
The organization reported no members and no revenue from dues, agency fees, or other fees in 2018. 
SEIU and the National Fast Food Workers Union seek to unionize the fast food industry to significantly increase union revenues by gaining millions more union members.  The “Fight for $15” campaign from which NFFWU sprung has pressured the government to override the distinction between independent franchises owned by entrepreneurs and the national branding companies; eliminating the legal distinction would ease a nationwide “card-check” unionization campaign under which workers could be driven into the SEIU without a secret ballot. 
Leadership Workplace Misconduct
Prior to the formal creation of the National Fast Food Workers Union in SEIU, the Fight for $15 was organized through a series of “worker organizing committees”—proto-labor unions created to comply with Labor Department regulations concerning union organizing.  Kendell Fells, a longtime SEIU employee, headed the largest, the Fast Food Workers Committee based in New York.  Fells would become the founding president leading NFFWU. 
Fells abruptly resigned his employment at SEIU and his leadership positions in NFFWU and the affiliated Fight for $15 campaign in November 2017.  Bloomberg News reported that Melissa Byrne, a former SEIU employee who later worked for Bernie Sanders’s 2016 Presidential campaign, had raised concerns about Fells’s conduct as early as 2011. 
NFFWU reported zero members to the Department of Labor in 2018; critics have characterized it and its predecessor groups in the SEIU’s “Fight for $15” campaign as professionally organized “Astroturf” rather than grassroots activism.  Fells had said that the SEIU’s process includes placing 150 protesters in front of a fast food retail outlet to shut the business down for days until they relent. 
Fells made misleading comments to a conservative “tracker” at one Fight for $15 rally, initially denying being a paid activist during a “March on McDonald’s” event. Fells claimed he was merely a supporter until the conservative tracker got him to admit his position in Fight for $15. Federal records indicate that SEIU had paid him $146,000 that same year for work as a deputy organizing director.
