My grand boss has communicated out an unrealistic expectation to the board that we are unable to meet.
My subordinate has complained to the board about my grand bosses conduct but won't elaborate to me what he said in his complaint.
The subordinate has a history of ignoring the chain of command and going straight to the top so his concerns are often ignored now.
However, in this case I think he has a valid point and I asked my grand boss what could be done to help us meet the expectations set, such as overtime and mentoring. My grand boss agreed to both but said no matter what we have to deliver on the date said.
I told my grand boss that my subordinate had put a complaint in about my grand boss and my grand boss responded saying that this has happened one too many times and that he wants my subordinate gone.
After discussing what has gone on with my wife, she said to keep out of it.
If I do so, the pattern will continue to repeat itself. So I am looking for a list of actionable points I can take away to resolve this situation and prevent it happening again if at all possible.
