Do you think anyone from the BoD would accept a job in a sinking business? I mean, would YOU (with your 'insider information' as an EC member) accept a job in a company if you wouldn't see it clear to be a successful company?
Most definitely. Most definitely for the second question as well.
Most board members work only a few hours per month yet get paid in the tens of thousands of dollars per month. Whether the company is sinking or not, they will get paid. Of course they would want the company to succeed to keep the money train going, but if not they would at least have had a good ride.
