Who likes to snitch? What's your personality like?

What kind of person is a snitch? He is a selfish little man. He is a man of duplicity. He doesn't work hard, but he is bent on climbing up. Whoever is better than him will try his best to calculate others, speak ill of others, sow discord and create contradictions. He often runs to the leadership office whenever something happens, reporting some unrealistic things and provoking the relationship between leaders and employees.
