Waterloo, Ontario-based Research In Motion has begun laying off workers according to a report from a local newspaper on Tuesday. The Waterloo Region Record reports RIM has already begun reducing its staff, though there is no word on how many employees have been let go at this point. Last week, RIM reported a weak first quarter and poor fiscal 2012 guidance that sent investors running for the door. RIM’s Co-CEOs also confirmed on an earnings call that the company would be reducing its workforce, though no time frame was provided, and that the launches of several upcoming BlackBerry devices have been delayed. Shares of RIM stock have fallen more than 25% since the company reported its earnings last week, and it is down more than 50% so far this year.
