I think you might just straight say "management skills" because that's bare minimum part of their fucking job to organize a schedule well enough so they don't have to have people running into overtime to get the job done. That is time management, too, because you're supposed to know how long it takes each employee to do shit, and you should be fucking organizing based on that.

I'm so fucking sick of skeleton crews. I'm pushing 50 and the last 25 fucking years has been nothing but skeleton crews where if one person calls out sick everything falls apart. Sorry, that's inefficient as hell. If one person calling out wrecks everything, then that means you're doing it fucking wrong and maybe you need one or two more people to help cover the gaps. I'm sure it makes them beaucoup bucks in the short term, but the profits from ruining your relationship with your customer base won't last. Eventually customers do get sick of being treated like shit. (Corporations are banking on all of them similarly treating you like shit so you won't have any real options that are better.)
