I appear to have offended, angered and upset a colleague from a different department who has to roll out a new initiative over the coming weeks. The changes will have quite an impact on my department and his latest directive was sent out on Friday and had several members of my team in uproar. They told me they were going to email their concerns and I didn't tell them not to because I felt they had valid points.
Late on Friday I also sent him an email in which I challenged, politely I feel, some of his ideas and explained why they would be difficult for us to implement. I also pointed out a fairly minor error he had made which was directly related to the project in question. I could have ignored it and perhaps should have.
Anyway, he has sent an icy reply today claiming he has been besieged by emails from my department and that we have misrepresented his views, which I don't think we have. He has also CC'd in two senior managers, which I feel is a little OTT, but on the other hand I am quite glad as it should mean I get a chance to air my views.
But I am now dreading seeing him tomorrow and don't know how I should approach him. We don't work together but I see him most days. He is not senior to me but I don't know him very well. I can't sleep for playing out possible approaches. How shall I play it??
