If I learned that the accidentally visible filename of the PowerPoint in that meeting was “EjectorSeat.pptx”, I’d be some combination of angry and alarmed about management’s attitude. That would be a definite “update my resume and call up some former colleagues for lunch” kind of moment at the very least.
I think people reasonably expect that when a company makes a serious decision that affects hundreds of people’s livelihoods, that they effect a pretty somber tone.
