Sadly, such an obvious concept but weirdly ignored by a lot of executives. I remember being at a company with "Don't be a jerk" as one of the top culture lines but one of the most senior executives was probably the craziest jerk you've ever met.
If you have to say "dont be a jerk", rather than just do it, what does that really say?
I wish I could say I’ve never forgotten that lesson, but the fact is I forget it quite often. I feel a little bit dumber every time mistake a value statement for actual values.
All that said, there is often more happening than we know, so I try to keep my own judgmental feelings in check.
