I have been in a new role for just under a month. A team has been put together to work on a project and are hot desking in our office. One particular member of this team is always seated next to me and he is really grating on me as he goes out of his way to make negative comments about my competence in front of my direct line manager and other colleague’s. He has gone as far as to call me useless and unhelpful. Admittedly I have made mistakes as I am new and still learning however, he’s not even part of my team it doesn’t even affect him. Essentially he makes me feel like crap. He is really pally with my line manager, constantly going on fag breaks together and sharing food. I try to ignore him but I feel like he trying to get me fired. AIBU to ask him what his promblem is?
