Microsoft has published a memo sent to staff from CEO Satya Nadella revealing that the technology giant will axe 7,800 -- just over 6% of its workforce. Many of the layoffs will be in the company's struggling phone division, and Nadella also revealed that Microsoft will take an impairment charge (read: writeoff) of $7.6 billion (GBP4.9 billion) on its acquisition of Nokia. What's more, Nadella said the company will take a restructuring charge of between $750m (GBP488m) to $850m (GBP553m) to push through the changes.
