It is concerning to see quite a few members in this topic agree with the feeling that favoritism is a problem, and I would certainly be interested in hearing more about how they came to feel that way if some were willing to fill me in through a private conversation.
Favoritism can be a tricky issue to nail down. The reality is those who associate closely with people in rank or positions are always going to be more likely to be promoted, not necessarily because they are friends but because those giving promotions will be more familiar with what those people do, making it easier to assess them. In this case being friends with someone and being aware of their actions and performance more tends to go hand-in-hand, which can easily give the impression of favoritism even though that's not really the case.
However instances of favoritism can still exist. The reasons for promotions matter, and all members of the same rank should be held to the same standard, friends or otherwise. If promotions are being given out without the effort being made to earn them, then that would be an issue worth hearing about and a bad habit worth breaking.
If you have a concern, don't be afraid to share it. Those of us in leadership are not omniscient, we cannot fix problems we are not aware of. At the same time, however, it is important to keep in mind that earning promotions, whether in OD or in real life, will often involve not just working hard but taking steps to ensure you are noticed and stand out from your peers. Ideally the Division Leaders should make their best effort to acknowledge the work and actions of all their members, to the best of their ability, but those members interested in advancing should also make their best effort to approach leadership and let them know that they *are* interested in working their way up and ask what they can do to help out or earn their place.
We are the progenitors of our own worlds, the protagonists to our own story. Just as a story could never progress without the actions of its characters, it is only through our own actions do we shape our world. To do nothing or say nothing is to accept the world for the way it is. In other words if your plan is simply to wait for leadership to notice you, or to notice the problems you see, then things are unlikely to change. You must take it upon yourself to take the steps needed to achieve the things you feel are important.
