I got blindsided/stabbed in the back today by Road Runner. I have spent, literally, hundreds of hours doing data analysis for her. I even worked 30 hours over the last weekend to finish the analysis so she'd have it for the symposium she's hosting this week. In the middle of a teleconference with some collaborators at other institutions, she had Bar Minion present the results of the analysis she's been working on. If you guessed that it's a variation of the exact same analysis that I just finished, move to the front of the class. This is especially hurtful because several months ago I asked Road Runner, flat-out, if Bar Minion was doing the analysis. She told me no.
Here's what's funny: I suspect that Bar Minion's husband actually did the work. During her presentation, she was asked a couple of questions that she couldn't answer. In fact, she actually flat-out said, "I'll have to ask my husband" in response to one of the questions. In summary, she was presenting results that she could not explain.
So, what do I do? I have managed to hold off on sending an email to Road Runner to let her know exactly what I think of the situation (in polite, PC terms). Basically, I have just wasted hundreds of hours doing work that I suspect will not be used now that she has Bar Minion's (husband's) work. At least I now have confirmation of the fact that I absolutely, positively, cannot trust Road Runner. I also think it might be time for me to reduce the amount of work I do with/for her.
Man, I hate working with cutthroat people.
