Rumors of the job cuts circulated over night, but now the big tech giant has confirmed the move in a memo sent to staff. The cuts come as the company looks to "align our cost structure with our revenue and where we see customer demand," Microsoft CEO Satya Nadella said in the memo sent to Microsoft employees. "We know this is a challenging time for each person impacted. The senior leadership team and I are committed that as we go through this process, we will do so in the most thoughtful and transparent way possible," he added. The figure represents just under five percent of Microsoft's total headcount of over 222,000 staff. Some employees will be told that they'll be losing their jobs today, with the remaining redundancies being made by March. Also: Why job cuts at big tech don't always show the full pictureThe memo points towards "times of significant change," parts of the world being in recession, and the rise of new technologies as some of the reasons for the redundancies. "These decisions are difficult, but necessary. They are especially difficult because they impact people and people's lives -- our colleagues and friends," said Nadella.
