I just had the experience of dealing with a difficult co-worker. The co-worker is less than competent in my and others opinion. I know more about her area then she does. She is constantly providing less than accurate data to our group.
We had to work on another project together. Once again the information she provided was only about 75 percent correct. I tactfully informed her for the descrepancies. Unfortunately there is a little turf war between our two departments. The work belongsin the other department but our upper management has recognized that we do a better job on critical matters.
We completed the project and was directed by our management to proceed based on our findings. We tried to keep the other group in the loop constantly with emails and updates on our findings.
My counter part was not to happy about being side-stepped again. Her thoughts become single-threaded and she becomes argumentative.
I cannot find a way to successfully deal with this person. In my opinion she is less than skilled and argumentative. I have tried helping her but she seems to have a chip on her shoulder.
Any suggestions?
