In the US, there's something called a class action lawsuit.
"As of July 1, 2010, Quiznos was close to reaching a settlement over the multiyear class-action lawsuit that covers nearly 10,000 of its current and former franchisees. The case comprises four separate class-action lawsuits dating back to 2006 which consolidated in 2009 — involved allegations by attorneys for franchisees that Quiznos Franchise Co. LLC and other entities with ownership or control of the Quiznos chain had violated U.S. racketeering and corruption statutes."
snarky and oversimplified, but basically true.
