Why are they still employed??
There are a TON of good, CNC operators around.
I wish that were the truth.

To expand on that comment:
There are decent operators around, however they typically (and in our experience trying to find guys) want far too much money for what they offer, and they tend to come from companies wherein they stood watch at one machine for an entire day twiddling their thumbs watching parts come out. I have 7 lathes, and 3 mills I am in charge of, and only I know how to operate/setup/program the majority of them.. I've tried teaching, but I can only repeat myself so long and I am just not confident in handing over my new machines to some of these guys. We've had guys come into interviews saying they can do this and that, "part to print" as they say, but then you get them on the floor, hand them a print and say "make it" and they'll stand there as clueless as rodrigo is when it comes to braking.
We have one guy here right now, lots of experience, but he is slower than molasses and even though hes been doing this for probably 5x longer than I have, he still needs guidance, wants you to double check everything for him even though hes already quadruple checked it, and needs a pat on the back now and then. My boss cannot stand it, he has made zero money off of this guy and he is very vocal about it to me. But we need him because at the end of the day he gets parts running.
The issue is that my boss has hired more "workers", "laborers" if you will, that just dont know a thing, dont care to know, and just want to punch in and punch out and dont care if they make $12/h for the rest of their lives.
I know we need more talented skilled people, but at the end of the day, those people are very hard to come by, and most of the time they dont fit into the demands of our shop. Lots of guys want to and are used to stick(ing) to one machine and one machine only, just punch in and out, with no real care in their work. At least that has been my impression over the past few years in this industry.
I have jobs where I have to hold a few tenths, and no matter how much I stress that the part cannot very in circularity by more than a tenth and cannot vary in its diameter by more than a few tenths, I'll still come in at night and find parts out, or come in in the morning to a night of completely bad parts. We run a few hex jobs and when those bars are bent its a real problem; I've pretty much taught lessons on how to check the bars, yet I still find myself pulling bars because of extreme bends/kinks.
It can be very frustrating to say the least most days..
