Is this ethical/unethical?

Is the use of power (in an organization) to obtain 'personal' objectives unethical ? if u agree...pls gv me reasons. If no, consequently too.
If you have to ask if it is ethical how can you honestly believe it is ethical.
all right its definitely frowned upon to say the least, but we do hold politicians to better standards than most people (and I am assuming your talking about government and politicians), the guy who uses free telephone time at work, if he became a politician would most likely be a corrupt one (or one that go for personal gain). Its easy to point fingers at those in power since they are in the spot desk light more often. I find that the average person will do more to help themselves beside politics, as politicians have to compromise. But going for personal gain and the goal of the company might not always be separate goal. I hate to pick words, but it would depend. I think that if the personal objectives are fully consistent with the organization's objectives, it would diverge than if you are sacrificing the organization's objectives for personal objectives.
Yes, it is unethical. Power in an organization is intended to be for professional purposes, and most positions of power are reserved for professionals who are supposed to behave as such. Personal gain is not supposed to enter into the equation. When it does, you attain things like the Enron scandal. It happens all the time, but when it happen on a large scale, people discern it more.

Here's an example. Pretend you are a police commissioner and you see your childhood nemesis or the bully who use to beat you up walking down the street one day. If you have him arrested on bogus charges and thrown in prison simply out of your own personal vengeance when he was in truth innocent of any crime, you would be using your power in the organization (the police department) for your own personal gain (vengeance). Does that sound ethical to you?
