Did it? Is there any documentary evidence? And, if it actually did occur, how often did it occur? I'm skeptical.
Let's say Microsoft employees did throw chairs at walls in the 90s. You can bet management would pull the employees doing that aside and read them the riot act. And get them to pay for any repairs to the walls.
Whatever caused them to start doing it probably had an expired certificate . . .
Nadella is a different type of CEO so the culture will follow his lead. I doubt throwing chairs is one of his go-to moves. He has other ways to make his point.
