RIM's current chief Thorsten Heins has had to make some tough decisions in the first few months of his tenure -- and he could be making some particularly difficult choices about trimming the rank and file within the next two weeks. Assuming we take the claims of several contacts for Canada's The Globe and Mail at face value, "at least" 2,000 jobs are being cut on or before June 1st. The numbers could climb higher at that: Reuters is bracing for as many as 6,000 layoffs, and has described an unhappy routine of "Goodbye Thursdays" where more recent hires are let go. RIM has turned down comment on what it calls "rumors and speculation," and we'd hope for the sake of those possibly affected that it's not true. Having said this, it's hard not to imagine Heins wanting to streamline the BlackBerry maker as much as possible to adapt to shrinking market share and keep the company afloat until BlackBerry 10 potentially spurs a revival.
