They mumble so they can create the "No one listens to me" victim-status They don't pretend to be over-worked, they just don't know what work is. If it isn't easy, they've never done it. So a regular workload is overwork to them. Not an excuse, just an explanation. It's my reasoning for never hiring fatties: they do 30% (max) of a job and complain that they're the only one doing anything. It's toxic to a work environment. They sigh all the time because their lungs are compressed beyond belief by gravity and ham, and they struggle to oxygenate their brains. Never trust anyone who's out of breath. Normal humans can regain their breath more quickly after a mile run than fatties can after pounding a twinkie.
