I know a manager who was master of this technique - he did not read any email, nor do anything.

Would not make a single decision.

All his projects failed and those around hated him, there was a lot of joy after he was fired. This lack of decisions costed the company a ton of money.

This guife is maybe made for the rare few who end up with a clean inbox every day.

I don't think he was the master of this technique after all.
