So does this mean that I can then do:
Class BusyBoardMember implements Employee, BoardMember
{
function position() {
// code for Employee implementation;
}
function position() {
// code for BoardMember implementation;
}
}
And if I only implement position() once then it will return an error?
This seems more than a little confusing, and like it could cause serious
mistakes down the road (during maintenance, etc)

I would imagine priority would be based on the order of the named
interfaces. Thus in your example it would use the Employee position()
method.
