Research In Motion has started to lay off employees, Bloomberg said Wednesday. We first heard reports that the BlackBerry maker was going to reduce its staff earlier this year when the company said it was going to explore new strategic options and had plans to restructure in an effort to save $1 billion. Some estimates suggest the company could cut as many as 3,000 employees. “RIM has committed to achieving significant efficiencies and operating cost reductions over the course of this fiscal year,” RIM spokesperson Tenille Kennedy told Bloomberg. “Headcount reductions are part of this initiative.” RIM also laid off 2,000 employees last July.
