Well, it probably depends on the type of "Senior Management" gossipgirl. Those few (very few) in the very upper echelons of power are remunerated to an extent that no level of medling would dislodge them from protecting their positions, at any cost! Just read the annual reports, you'll see what I mean.
As for other Managers? They may at one time thought they were in the inner circle, but in reality they are considered as easily replaceable as the rest of us! Like experienced pilots, they grow on trees don't they?
