It's gonna happen, because they're your boss. You're gonna be collaborating, and you're gonna have some killer idea, and all of a sudden it becomes, not your idea, but his or her idea. Your boss is inevitably gonna take an idea of yours, and you hope give you credit, but, inevitably, take it on as their own. How you deal with it is you let them know that you know this idea came from you. You don't wanna own it possessively, you wanna say, "Hey, that idea was generated out of a team discussion and wasn't that fun, isn't that interesting" and you just wanna make sure that they know that you know that they have taken that idea and have represented it as theirs. That's a part of work; I think at the end of the day, that's what happens. If you keep generating great ideas, you're gonna continue to be asked into the big meetings and people are gonna notice that in fact the ideas are coming from you. At the end of the day, you can take it as a compliment that your boss has stolen your idea, you just wanna make sure that he knows that you know.
