I have been located into a company that has completed a slow transition from local IT support to being outsourced. My colleague has been there for 10 years and is part of my outsourced company.
I have been put in charge of a big project but he is always around taking control and pushing me out because he is obviously in competition and feels with the change he might lose his job.
I told him nicely to continue with his job and leave me be, but he refuses and continues to be present.
If I forced my way into someone else's project, I would be sure to be directly and harshly told to go away but I don't want to create conflict with someone I work with everyday. How do I approach this?
