Yesterday I wrote a blog about communication with your ex-employer and what I recommend you do and NOT do.
I asked, “Why do I like suck-upiness?” Why do I recommend it?
I recommend it because it works.
Kindness almost always works better than being a mean old jerk.
Being gracious almost always works better than a threat.
Honesty almost always works better than secrecy.
So that is why I don’t recommend threatening emails or letters in the course of non-compete work. This is why I recommend something nice that makes everyone feel like you are not a threat.
