Someone comes to you and says, "my job is pointless and should not exist."
The conclusion is drawn, "Actually their job is vital and their self-report is deluded."
Further, how can we trust our perception is the better measure of the value of that job? If the person performing the role can't even assess the value properly, how are they providing that value?
go remove some guys that do legal compliance stuff and when the random inspection happen years later, you'll find out that maybe it would've cost you less to keep that employee.
Planes can keep flying without a pilot for quite awhile, until they run out of fuel or crash into a mountain.
Bad news: you have been rejected from consideration for any work related to realtime/life critical systems.
Good news: you may have a future in politics, at least in the county I live in.
"What will happen if this person stopped doing their job?"
"Oh the important monthly reports will stop going out."
"Oh, okay, we better not have them stop doing that then."
I submit that not only can we, but we must, admit that in some individual cases the person in the position knows best, and in others, they don't.
Or maybe, absent other evidence, it might make more sense to tentatively take people's self reports at face value. Or at least hold off backing some particular elaborate alternative which involves people being wrong about the things they have most information on.
I take it as the software version of virtue signaling.
The conclusion is drawn because presumably someone thinks they output enough value to continue paying them for their work. That person might be wrong, and maybe some PE firm or consultants will come through and cull the chaff to capture the lost expenses but the person themselves doing the work probably doesn't have the full perspective.
