Nah, they’re just pissed because now they have to work harder.
A manager shouldn’t have to work like one of the minions. That’s the whole reason why they can be so critical. If they start working like everybody else; fatiuge will kick in and thoughts will start to enter their minds like “Ah, screw it! These tasks aren’t necessary and neither are these!”
It’s kind of like the football coach. If he actually had to run laps with his players; I’m sure he might think 20 laps are enough as oppossed to 30.
