I don't like the idea of work politics, but I've just partaken of some and feel a bit grubby now...someone is publishing using a theory of mine (quite a good one, if I say so myself), and I suspected that they might "forget" to mention to anyone that it wasn't actually their own theory. So I emailed this person, copying my supervisors in, with some advice and a copy of my original work on this...feel a bit sneaky doing it though. What would you have done?
