Microsoft has eliminated approximately 15,000 roles since May. The company’s CEO said layoffs are the “enigma of success.”

Microsoft CEO Satya Nadella didn’t send a company-wide memo when the software maker laid off as many as 9,000 employees earlier this month. Now, Nadella is finally addressing what’s on many Microsoft employee’s minds: layoffs.

Microsoft also spent around $9.7 billion on stock buybacks and dividends ahead of the recent mass layoffs, but Nadella says the company is 'thriving.'
