I found out from a member of another department over an informal chat (more like grapevine) about how they know and think about appraisals and reviews are done for my team.
There were no names that he spilled out, yet the information that reached the person was true. It was regarding an important management decision in the past, which was about an individual and was strictly confidential.
I feel that this is a leak of confidential information and make the management aware. I also believe that such talks are spoiling the reputation of my team.
What I'm not able to decide is whether it is really my business. I'm not a team leader but an individual contributor in my team. Should the management know about this information leak?
Just one thing to add- the managements of both the departments are completely different.
