I have a problem which I'm not sure how to handle. I work in a "creative" industry that combines usage of very specific software with individual approach to the specific project. So, technically speaking, we are all "artists".
Yesterday, after my part of work has been approved, I've got a request from the top supervisor to touch base with my colleague regarding his part. I've politely approached him, showed where he can find approved version and mentioned that he is welcome to use my materials or write/call me if something is not clear.
He answered that he will do it his own way, but it was perfectly clear that at least he saw my version and understood what was needed to be done. So, I have answered to the supervisor's message, claiming that I've talked to that artist and we were all good.
Later, the artist has submitted his version (which was different from approved one) and supervisor came by his desk with notes to give him an idea of how it could be done.
As it happened after my message "all clear", I've tried to talk to that artist (again, very politely and without any pressure) and mentioned that he is more than welcome to use what is already done from my part.
In response to that he started swearing loudly using "F word" as noun, adjective and verb, telling me I shouldn't talk to him, that I'm not a lead artist, calling Jesus for help and so on.
I felt really embarrassed by response and the fact other people heard he was talking to me in such manner. Same day, when supervisor talked to me about certain part of work, I have mentioned that unfortunately I can't effectively communicate with that person and explained the situation to him. As one of the managers was present at that moment, I have offered to talk to that guy (he was also near by). After this, he turned around and walked away without saying anything to all of us. Manager told me not to worry about it and assured that she will talk to him in person.
The question is, what have I done wrong and what should I do next? How to resolve this situation? What is your experience/recommendations about approaching people with big ego? Thanks a lot.
