I am not a director and have no direct reports- and rarely have 'people' issues- but have 2 thorns in my side lately.
I have used your feedback model for the 1 co-worker who has been difficult and it seemed to work well. Not my main concern.
I have another co-worker that I am having issues with. He would probably be described as a high D and is very abrupt, rude and hard to collaborate with. He gives his opinion- but if you try to compromise- he argues then goes into an apathetic state of 'whatever'.
He is new to the company- but a seasoned marketer and has been in the industry for years. His experience/ knowledge is not at issue- it's his ability to contribute to a team project.
We are in the middle of launching a major, high profile marketing campaign incorporating 3 products- for which he has responsibility of 1.
Early on, I took a leadership role and advocated for the program. The program has picked up steam, we got special funding and the other product managers and I, started moved the project along- working VERY well together.
I am now the official team leader- and I have to rely on the new PM for some things. There are 2 other product managers also on the team and all pitch in to collaborate and take on pieces of the project. The 3 of us have done a bulk of the work- while the new guy refuses to volunteer for tasks.
Additional background: We started the project before this person was hired- so he was kind of added to the project. He and I share a supervisor and her direction to him is that this is part of his job responsibility. Also in explaining the teams experience with his behavior to her- she can see no issues (because he acts differently when around her) and feels it's just a difference in work style that we must work through.
Things seem to have gotton progressively worse regarding his attitude towards the team. there was one incident early on where he blew up irrationally (think of the scene in office space where the guy freaks out screaming he's a 'people person')
After walking on egg shells for a while and trying to make him feel like part of the team- all team members have become fed up with him and have no interest in dealing with him anymore... His negativity, apathy and rudeness is very disruptive in team conference calls. None-the-less, due to individual product markeitng responsibilities- we are forced to rely on him.
Our big launch to the sales organization is coming up soon!!!!
