There is one department in your office which is you can get all the news of your office. This department has the insider information about your colleagues, about your boss, basically everyone. Its the HR department!! One thinks that the HR is the devil when it comes to policy making, determining designations, salary increments and all but once you work your magic on the HR guy/girl nobody can stop your progress.
You may not even know the breaking news of the day, but you would always know what your colleagues are talking about; anyone who speaks wrongly of you or has a complaint gets to your ears first. Your conveyance expenses get curtailed a lot when your friends with your HR; you may live ten mins from your office, but that does not mean you hire an auto the friendly HR is on its way. Perfect attendance awards shine in your trophy shelf in spite of you missing out on a couple of days; it's all dust under the carpet. You're never late due to sleeping, you're stuck in some god-created traffic. Gossiping comes naturally with no one ever having to find out what you just said about them.
So be good friends with your HR and see the change it makes!!
