Funny, I took a training class for my day job about ethics (totally unrelated to recovery) and the teacher asked, which of these three organs are the smartest, our brain, our heart or our gut.
He said gut. I agree. If something feels off, it probably is. I don't have any words of wisdom on how to react, except to be cautious. When it comes to career behavior, all I can say is do what you think is right, CYA (cover your behind) and try to spin that team towards solutions rather than focus on the problems.
Best wishes to you, Greet! Career politics suck but those that find a way to move forward in spite of the negative contributors move up. And yes, your HP will certainly guide you in the right direction!
