They're referring to jobs where you have overarching goals and deliverables but aren't logging actions to the event, or to the hour.
I've had jobs like yours and steady, dependable, maintainable pace is the way to get through the week. Don't over promise, don't look available for random new tasks.
At my current gig I have tasks issued at the 2 week level, and aside from very rare requests for assistance or discussion, I'm left to my to-do list, and my predetermined commitments. If I consistently meet my commitments, and show up for scheduled meetings, no one gives a shit when I actually work. It's great but requires the right environment.
It is. You should try to move to a career where you sell the results of your labor, not the time it takes to achieve them. Easier said than done, I know. Good luck!
I'd straight up tell a boss that asked for unpaid overtime that their failure to allocate resources is money out of my pocket if and only if you want to hear from the DoL.
Unfortunately, many jobs that do this are salaried exempt.
Now, whether they are miss categorized is a different story. That's why my wife's old workplace is going to get some attention from the IRS and DOL when she finishes her month's notice.
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.)
