There are two types of People in Corporate world, People who manipulate and People who are honest. Whereas People who are manipulative are thought to be smarter and People who are honest are thought to be as dumb, And they don't get promoted or they don't move up the corporate ladder easily as they are the ones who are taken for granted as they are good people, So the management knows that they are explainable by giving a reason or an excuse, Whereas a person who is manipulative will not stick if he doesn't get promoted or recognized, So he/She gets promoted.

When that kind of thinking exists in corporate world then a person cannot remain good always and say that it's ok, So what he will do? Either he will leave his/her job or he/she will fight against the system, Well if that's is also not enough then the only option left is to himself/herself become manipulative and succeed at life for a shorter period of time, Just to show people around that being good doesn't mean that they can't change but it only means that they are giving time to other person hoping that he/she will change.

But when that doesn't happen then it's time to draw the battle and you yourself become manipulative and explain the other person in their own style. Unless and Until a person suffers he/she doesn't realize what they are doing wrong.
