All of us should insist on being treated fairly — to stand up for our rights without violating the rights of others. This means tactfully, justly and effectively expressing our preferences, needs, opinions and feelings.
Psychologists call that being assertive, as distinguished from being unassertive (weak, passive, compliant, self-sacrificing) or aggressive (self-centered, inconsiderate, hostile, arrogantly demanding).
Because some people want to be “nice” and “not cause trouble,” they “suffer in silence,” “turn the other cheek,” and assume nothing can be done to change their situation. The rest of us appreciate pleasant, accommodating people but whenever a nice person permits a greedy, dominant person to take advantage of him/her, the passive person is not only cheating him/herself but also reinforcing unfair, self-centered behavior in the aggressive person.
