Complaining time

[nattalie]

I need do this because I feel stressed. Since 2 weeks I hold my coworker complaining about everybody here and talking if the only one who does the things is him. He criticize everybody and all the time says they all are wrong. He's trying to know every single thing that happens here and he stopped to copy me in the mails he sends to sellers but of course, every time he needs to do a quote he's asking for help to me.
I don't like the way he's acting. When there is any problem instead work with the team to fix this he talks shit about they and starts to look for who is to blame. He has lack humility and I hate ppl like this.
