Management and Power

A scripture and saying that is often quoted in my church is "39 We have learned by sad experience that it is the nature and disposition of almost all men, as soon as they get a little authority, as they suppose, they will immediately begin to exercise unrighteous dominion. (D&C 121:39),"  This phrase often surprises me when I see it in action.  Being someone who is a management position I often have to remind my self of this very thing--Power Corrupts.  

Part of my job is developing new managers and leaders and then have them do the same.  But I find often when someone gets a little power things change.  They have a concept that they are entitled to certain liberties or rights over others.  Things that if they saw their employees do they would freak out.  For example one employee I had pushed hard a policy on the floor and even watch as we terminated employees for violating the policy.  When all along she was violating the policy!  She was shocked when I terminated her on the spot.  

We are tempted to always take advantage of what have.  Why?  Why are we so easily corrupted when we receive even a little power?
