Recently a member of one of the teams at work came to me with a concern. They had a message out of the blue from an assistant manager asking them about their manager and their managing style. Asking if they like having them as a manager and if they feel supportive. Now this person has an issue with said manager, doesn't like them and often says underhanded comments about them in the workplace. There was a particular comment in this text exchange saying some ppl don't deserve the titles they have. Now this made my colleague feel like he was being set up to say something negative about this person and their direct supervisor. They came to me asking what they should do and I told them to take it to their manager. Now I didn't mention anything to anyone else and the manager confronted the person. Now it has been deemed that it was possibly also aimed at me which I don't care about as this person needs to look in the mirror and see their own faults. This person and myself both are under a different manager whom said person is best friends with. My manager has not looked at the messages and has gone by what this persons said reasons were IE I wanted to make sure you were ok and the title comment was about another member of staff who has left. I'm now being questioned as to why I didn't go to the person (as it has come out that the co-worker seeked my advice) and ask them about it and why I didn't go to my direct manager. I felt this was going to be a biased view point had I gone to either so let the other manager deal with it. My question is did I do the wrong thing? I felt terrible but I don't do confrontation and felt had I gone to to person in question it could be seen as bullying as she has tendancies to cry alot at work. I didn't go to my line manager as they already have a very close friendship with the person of concern and I knew this person would be blindly defended. I'm feeling a little concerned about how to go forward.
