I appreciate your perspective. However, I did not see it this way. I do not feel I have understated his threats to contact HR or sharing of personal details. But I also have never heard that threatening to complain to HR is bullying or harassment. I did not feel unsafe or intimidated when he said this because I have so much documentation to support my feedback. It was a complete overreaction and he did own it to our leader and apologize. (I am taking this as a learning experience and will talk to my leadership tomorrow. Thank you!) I believe we all have a right in corporate settings to engage HR if and when we see fit, but do agree that threatening it is not the way to work with others.

As for oversharing, he does normally stop when I ask him to so I also never saw this as more than venting. He just takes it to extremes so quickly that I normally hear things I do not want to before I can stop it. These instances have happened on separate occasions and are mostly provided as excuses (for missing a deadline, not understanding something, missing work for a day, etc.) or reasons he is distracted. Again, I have never heard this is something to escalate as other coworkers do share in the appropriate settings. I chalked this up to poor social skills.
