 On May 17, 2004, Starbucks's workers at the 36th and Madison store in midtown Manhattan organized the first Starbucks barista union in the United States.The union drive had its origins in barista's complaints that a starting wage of $7.75 an hour was not a living wage in New York City and that Starbucks refused to guarantee regularity of hours per week.The union has also joined with Global Exchange in calling on Starbucks to purchase at least 5% of the store's coffee from fair trade certified sources.
