Not really. Worked for 5 companies, 2 were ruled by fear culture (including an explicit stack ranking of employees every 2 quarters, with the bottom ones being fired), one by desperation, one by... inertia maybe. The 5th is Google. Still can't figure out what it's ruled by exactly, but absolutely no fear, yet it mostly works. That's why I'm sticking around, I guess. I've moved teams and orgs quite a bit, so I don't think it's just me being lucky with a manager. If there is fear, it's in quite isolated pockets.
