Posting here for traffic as I have a meeting this morning and need advice asap.
I had a work dispute with a male colleague that has recently moved from one dept to ours because he is currently under investigation in his dept for a separate incident - long story won't go into that.
He's come onto our dept and doesn't want to be here so makes things incredibly difficult by being purposely slow, not doing as he's asked, talking for hours on end and disappearing to the toilet for half an hour at a time.
I came into my shift last week to find that said colleague had left the area looking like a bomb had hit it, not done any of the work he was asked so it was all left up to me and I was told by another colleague he had spent all evening chatting and in the canteen. When the colleague came onto shift that day I joked saying what an earth had he been up to on the last shift as it looked like a bomb had gone off. He asked what I meant and I said about the area being a mess, work not being done etc and how I had rushed to get it all up together as well as doing my own job. The colleague went beserk and said I was unprofessional and if I had a problem with his work I should go and the manager not speak to him directly. Another colleague heard the exchange and said that I had not spoken out of turn or aggressively.
I've since found out through the week he has gone through all the colleagues in the building and asked them - what they thought of me, had they hadn't any run ins with me previously, told them that I had been horrible and unprofessional to him and basically slagged me off. I can see people whispering about me and I've been told that other colleagues have joined in with the slagging session and they all crowd round this colleague and have a slagging off session about me.
I was furious and immediately asked to speak to the HR manager to arrange a meeting to make a complaint about the way this colleague has been going round "interviewing" everyone about me and also fabricating what actually happened to make me look awful. The meeting is this morning. I've mentioned it to people that I'm taking it further and I've been met with responses that I should just leave it, it will cause an atmosphere in the dept, it will make me look like a troublemaker as this colleague is already in trouble in the other dept and so on. This colleague is popular.
Now I'm doubting myself and think I'm making a mountain out of a molehill. WWYD? AIBU to make the complaint to HR?
