That someone could come up with a #1 is remarkable by itself. Shana Lebowitz:
American workers’ top complaint about their bosses is that they don’t recognize employee achievements. Some 63% of employees cited a lack of appreciation as an issue with their managers.
To me, that management technique is a no brainer. I’ve worked for experienced managers who never heard of Maslow’s hierarchy of needs, and for the few who had heard of it, most dismissed it as babble speak.
