direct supervisor

I have been at this forum for a while and read many complaints about direct supervisor. I have complained about mine as well, mostly about playing favorism, not recognizing my value etc. Because of the power fight here, my supervisor is looking for another position. Of cause this is secret. It was a coincidence that I learned about this. Then I start thinking about my life in this group after his departure. The sky is falling. That is how I feel. My friend used to say the same thing about how he felt when his supervisor left. I did not believe him at the time. Now I do.
