One of the most important skills you learn as a manager is to not jump to conclusions with people stuff.
Oh you were late again you don’t give a damn! Turns out they literally just had a death in the family.
You’re complaining about lunch again, get a new thing! Turns out they have a super common food allergy and 70% of lunches don’t work for them.
Hey are you nodding off in this meeting! Well, turns out they just had a small stroke.
With a big enough organization, death, illness, and hardship are happening constantly, so you really learn to ask before you react.
