The biggest chunk of job losses, though — about 12,500 — will come because of the Nokia deal. Mr. Nadella has singled out Microsoft’s mobile business as one of his top priorities, but the layoffs announced on Thursday amount to a significant retrenchment in one area of that market.
The vast majority of the jobs being eliminated will come from the Nokia groups, though some will come from overlap at Microsoft resulting from the deal. Microsoft said 1,100 job cuts would come from Finland, and 1,800 from a Nokia factory in Hungary. The result is that Microsoft is letting go of nearly half of the 25,000 people who joined the company from Nokia.
That deal, the brainchild of Mr. Ballmer, has been unpopular among some Microsoft employees and investors, who view it as a dangerous adventure into hardware, a business beyond Microsoft’s expertise.
