When an individual tends to jump into parent mode (critical or over nurturing) they create an opportunity for an individual to act like a child (dependent, whiney or rebellious) or vice versa. But adult (rational) behavior creates adult behavior.
For Example: A manager might say “I asked you to be done with that by Wednesday and now it’s Thursday. I’m really frustrated now” (parent) and a direct report might respond with “I’m sorry but it wasn’t my fault” (child).

Great insight. I have been leading/managing teams by following my gut feeling. But verifying the “correctness” of my approaches by the results is not a reliable approach. Theories like the above provide reasoning of why I should be saying/doing some things while not saying/doing some other things.
