Don’t Confuse

ThisvsThat
Hearing (physical)Listening (attention to meaning)
Paralanguage (voice)Kinesics (body)
Empathy (understanding from their side)Sympathy (feeling sorry for)
Assertive (firm, respectful)Aggressive (firm, disrespectful)
Collaborating (win–win)Compromising (both give up part)
Avoiding (no one’s concern met)Accommodating (other’s concern met, own given up)
Johari blind (others know, I don’t)Johari hidden (I know, others don’t)
Escalating what is beyond your powersPassing the buck on what is within your role
Firmness on rulesHarshness towards people
Favourite MCQ trap: the strict-sounding option
“Suspend immediately”, “issue show-cause at once” or “call the police” look decisive but punish or escalate before understanding. Unless safety is at immediate risk, the best option listens, checks facts, acts within law and follows up.
Favourite MCQ trap: empathy as leniency
Waiving a mandatory requirement out of sympathy is not good interpersonal skill. Empathy changes how a rule is applied — explaining, helping, speeding up — never whether it is applied.
