There was this problem I had with a team member in my previous company. There was this team member that likes to make use of the company resources without sharing with others. Each and every time any of the company resources is handed to her, she makes use of them for her own personal use without letting any other person on the team know about it. Somehow, we get to discover that that was a problem and nobody was ready to talk to her about it, about how her attitude has been affecting the team overall. At first, I didn't want to approach her because I didn't want it to look like I was the only one that was able to approach her and talk about it because nobody else was ready to talk about it. Over time, it became a problem and everybody else started to grumble and nobody was ready to talk to her. So, I started to bring the matter up to her and tell her how her attitude has been affecting the team. Somehow, she apologized and said that she didn't really know that it was affecting the whole team and started to change. This made me realize how important it is to have conversations with people because they might not really know that what they are doing is bad.
