Kochan was quick to express dissatisfaction with the term "alt-labor," which suggests efforts beside, or distinct from, the traditional labor movement. In fact, the movements have overlapping goals, and long-standing unions often support alt-labor organizations. But terminology aside, the need for something like alt-labor is widely recognized. Andy Stern, the former president of the Service Employees International Union, argued in 2004 that, "we aren't going to rebuild the labor movement to what it was—that workforce and economy no longer exist." Instead, he said, "we need to transform unions."

The emergence of alt-labor signals the growing need to understand, and, ultimately, put in place protections for, the 21st-century workforce.
