Nerval's Lobster writes "BlackBerry is preparing to slice up to 40 percent of its workforce by the end of 2013, according to anonymous sources speaking to The Wall Street Journal. The layoffs will reportedly shrink the company's overall operations and affect every department. A BlackBerry spokesperson refused to comment on the matter to the Journal. BlackBerry bet the company on the success of its new BlackBerry 10 operating system, but its first two 'hero' devices running the software — the Z10 and Q10 — failed to make much of an impact when they arrived on the market earlier this year. On Sept. 18, BlackBerry also unveiled the larger Z30, which runs an updated version of BlackBerry 10 and features a five-inch AMOLED touchscreen and larger battery. Once a dominant player in the mobile-device space, BlackBerry seemed helpless to respond as Google Android and Apple iOS slowly but surely chewed away its market-share over several quarters. As corporations adopted BYOD (Bring Your Own Device) policies, a flood of personal iPhones and Android devices helped displace BlackBerry as a mainstay of executives and office workers."
