 Collective bargaining is a "moment in history", as Horowitz told Lehrer.Judging by listener phone calls, Lehrer suggested that the biggest problem freelancers had with the Freelancers Union (at the time, in 2007) was that they could not meet the organization's definition of freelancer, which requires that they work at least 20 hours a week in one of seven industries typically associated with independent workers.In recognition of her efforts to create a self-sustaining organization of flexible workers, Sara Horowitz was awarded a John D. and Catherine T. MacArthur Foundation Fellowship ("genius" grant) in 1999.
