I greatly admire a company that hires and promotes on merit alone, and I couldn’t agree more with that philosophy. The age, gender, race, etc. of the person I report to would certainly make no difference to me.

If he can’t count on me for that, then everything else I may do or say could be questionable in his eyes. But I also want to express my thoughts in a constructive way. So my goal in this case would be to see if my boss and I could make his idea even stronger and more appealing, so that it effectively overcomes any initial reservation I or others may have about it.

Good human relations would call for me to go directly to the person and explain the situation, to try to enlist his help in a constructive, positive solution. If I sensed resistance, I would be as persuasive as I know how to explain the benefits we can all gain from working together

除了would be as persuasive, 我能理解为情态动词would这里表示猜测外，其他句子里的would的用法都不太能理解，不知道只是表示语气的委婉，还是其他什么用法，请教各位老师！
