Francesc- are you in risk management? work for NASA?
I am at the edge of my seat..I'll be pulling for you. Everything will go fine..maybe not according to plan..but fine.
When I dropped the bomb on H bosses..I got a completely different response than what I expected. I thought my H was going to be crazed...he was actually embarressed and ashamed. He deflated like a balloon. Try to limit your expectations...your W if human..you cannot control the way she is going to react..just remain confident afterwards...no apologies...stay strong.
