You are not happy about colleague A who bad mouthed you behind your back.
When you talked to colleague B, you almost mentioned how terrible A was… suddenly you realize if you do this, you are no difference from A. You know that gossips at work are killers for trust, killers for productivity.
You are a sensible person.
We need more sensible people at work to build better relationships.
Sensible in action is reflection of professionalism.
Sensible is glue at work, at home and among friends.
