A mistake many managers make is thinking they are motivating people when in reality they are manipulating them.
Manipulation is a way for one person to get someone else to do something that is wanted or needed without the second person receiving anything significant in return. This method of getting others to do something usually results in a loss of true motivation. When people realize that they have been manipulated, it is normal for them to feel used or even abused because of it.
One simple way to avoid becoming a manipulator is to determine why you are asking a person or group to accomplish a task. If it is to get you out of doing it or to get something for free, there is a good chance that you will be using manipulation to get the job done. Examine the outcome of the process. Is it highly likely that the person who does the work will feel good about the job or receive some personal benefit from it? If this is not the case, you can assume that at least part of the process is more manipulation than motivation.
Money is sometimes a leaver of motivation. But it is not always money that is the driving factor of motivation. Dan Pink´s Youtube Clip:The surprising truth about what motivates us, is inteststing to watch! Enjoy! http://www.youtube.com/watch?v=u6XAPnuFjJc
