I've got a question. What's the best way to bring up instances where a co-worker has taken credit for your work? A little background. I am responsible for about 99% of my team's reports and presentations. I am the one who has to take the time to put all of these things together. Last week my boss, and his boss, visited a teammate while he gave presentations to his clients. One report, in particular, was illuminating and our regional manager was impressed. He wanted a copy of the report and how to pull it. My teammate called me the next day telling me that they had told him I had pulled it, and they'd get the info from me. So I gave him step by step instructions on how to pull said information. He said I'd get all of the credit. Normally I don't care who gets the credit, but this aggravates me. Found out last night there is a string of emails that went out giving this guy credit for developing this process. It was originally sent out to the team managers, and this guy even went so far as to reply with instructions. As I said, I don't really care who gets credit. I'll usually just laugh it off. However, this email went out to the region yet I was left off the chain of emails. Almost as if they did it intentionally. Long story short, I want to tactfully show this guy is a fraud. He has a history of doing things like this, and gets praise for work he doesn't do. What's the best way to go about it?
