<human>: Original post here: 

Short recap: I have a co-worker "Jack" who constantly tries to discredit me, bully me during meetings, and is very aggressive about getting into my personal space while arguing. He slams his fist into my desk, leans in over me while yelling and often puts down my opinion in front of others. Other colleagues seem to value my opinion/input and I've never had a negative review. My manager offered to change me to a project area.

So with the advice from the last post, I decided to push the issue once more with HR... It was not a productive meeting. They met with both of us separately and basically said, "You guys need to stick with your job description and if there are issues, talk to you managers and not each other."  They were not interested in hearing about how he acts during meetings, how he's endangered our project deliverables on multiple occasions, or how his negativity and anger issues have affected our team.  

I'm feeling pretty discouraged because they were not supportive of my proactive work style at all. I'm the kind of person where if something is lacking, I jump in to help the team get organized or back on track. I'll do work outside of my job description if it helps get the project done. This attitude has made me successful and well liked with my other colleagues. 

Jack is the only one who seems to feel the need to belittle my opinions or make negative comments about my work, but it felt like HR was telling me to step back and just do what I'm paid to do so that I limit the times where I might run into Jack. They didn't really address his bullying or aggressive behaviour at all and kind of made it sound like it was my fault.  :/

So I'm not sure what to do now. 

I could still change teams, as my manager offered.  I could stay and see what happens (a few of my colleagues think that the company will not act on Jack's bad behaviour until its time for annual reviews). Or, I could leave for a different job.

Right now, I'm feeling super disrespected by management and HR and it's very discouraging.

Can you provide a brief overview of the text?
<bot>: Raising the issue of my evil co-worker to HR again did not help. I've been told to keep to myself and just do my job. What now?
