I recently started a new job, and am working as part of a team with two other new employees. The company is in my opinion a good place to work with high levels of professionalism and great employee benefits compared to other places I have worked.
However, one of my new colleagues is incredibly negative. He has told me that he is not interested in the work, he is not a team player, he can't see the point of various exercises or team building activities. This is not my opinion of what he thinks its actual comments he has made to me!
When we are in meetings with no management present he acts bored, complains and has even held up messages behind our other colleagues back slagging her off (without her realising). But when management are around he acts positively and wants to take on responsibility for tasks.
I can't make out why he is acting like this, I've encountered negative people the workplace before but normally they are long standing employees that have become disillusioned. What would make a new employee act like this and, more importantly, how can I prevent this negativity rubbing off on me and preventing us from building a successful team?
