My boss has a new boss. And, it's suddenly sent my boss scurrying to prove herself - e.g. excluding me from meetings I was normally a part of, but taking my work and presenting as her ideas, spending a lot more time in areas that, up till now, I was allowed to continue working on. My peers feel the same way.
My mentor within the company tells me that I add a lot of value because of all the specialized expertise I've brought to the company in the 10 months I've been here. And, he also tells me that my boss will likely be moving back to her prior functional area. I'm not seeing any signs of this yet, but all the weird exclusionary stuff is really sending the wrong message to my directs and their directs.
So, I realize some of this is about "survival politics". But, I'm not understanding the weird exclusionary and credit-taking tactics. How do I address this? Talk directly with the boss? Ask for a skip-level with the boss' boss so that I can at least make myself known? Ask to be at the meetings where I was included earlier? How do I make my contributions also noticeable to the new uber-boss?
