I was looking for something in Slack today (for information I needed, wasn't snooping but happened to put in the right keyword) and found a temporary channel where HR and recruiting were discussing a role they are in the process of filling. I assume these channels are normally private but this one was not. One of the people they're interviewing is someone I work with currently. We haven't worked together for very long but have a positive relationship. The feedback they had was rough (and IMO not completely fair but probably other people who gave feedback have worked with him for longer than I have). I told a personal friend, no work connection, about this work drama and she said to send my colleague the link. Now I'm torn- I don't want to kick a hornet nest at work, but also the feedback might be helpful for his career and I don't know what kind of feedback they'll give him as part of the interview process. Also, I definitely wouldn't send him the link; I'd invite him to a meeting to talk or something else where the company couldn't snoop and read! Edit: Woah I went out of town for the 4th (American independence day) and came back and this post had blown up! I appreciate everyone's input but I won't be able to respond to each post. I heard the feedback loud and clear and won't mention anything to my colleague! I knew one person who was in this channel so I waited until we had a one on one meeting and mentioned it to them. They said they would take care of it; I assume everything is locked down but I haven't searched again.
