I had a disagreement with a colleague over a year ago and was written up in the fallout. I competed the probationary period that came with the write-up 8 months ago and had assumed that it was all behind me until today. My manager basically told me that he couldn’t let me introduce our new data collection tool to this colleague because of our past. It doesn’t make any sense to me as I’ve recently provided her with feedback on a data related task (after he brought me into the email thread) and have made organization wide recommendations about user profiles which impacted not only the activities of this person but many in the company. It just doesn’t make any sense to me, I was pretty sure this was all behind me until today. I have to admit I’m kind of crushed by the experience and am starting to look elsewhere.
