When you are working your way up the corporate ladder, one of the things that you are going to have to do is learn how to be a good leader. Showing good leadership skills will allow you to prove to your superiors that you are worthy of being given more responsibility than you currently have. You will realize, once you start behaving in a way that will make you seem like a good leader, that the hard part isn’t getting a promotion in the first place. Rather, the hard part is justifying the leadership position once you get it, because being a boss is not as easy as it sounds.
There are a few tricks that you can use to be a good boss. First of all, you need to learn how to deal with conflict. When you put a bunch of people in a room together, there are bound to be moments where these people are going to end up getting into conflicts. This is just human nature. As a boss, it is going to be your responsibility to deal with these conflicts. The problem is that you can’t just pull out an employee write up form and punish everyone involved. This isn’t going to work as a long term solution. Instead, try to be a mediator and deescalate the situation. It is also important that you be as fair as possible. What this means is that you need to hold people accountable for the things they have done. If someone has been unfair to one of your employees, it is essential that you back the victim up.
All in all, it is fair to say that if you are a good boss, the people under you will be working efficiently. This is the single biggest indicator that you deserve your promotion.
