Yeah, to be fair, there exist employees (some of whom are managers) who could not be replaced and their absence would improve productivity. So the bar for “can this replace any employees at all?” is potentially so low that, technically, cat’ing from /dev/null can clear it, if you must have a computerized solution.

Companies won’t be able to figure those cases out, though, because if they could they’d already have gotten rid of those folks and replaced them with nothing.
