Sounds like someone I knew at one airline a few years back, before they made the move to big-bad Indy, whom had I had done his comp check, he wouldnt have passed it (hell, he'd probably still be trying to pass it); he only passed his CC from the D-SOC because we needed a warm body on the floor because of inadequate staffing; and thats all this individual is, is a big, warm body.
I mean, I remember one day when I asked him the question to something simple, like how to 3585, so he reaches for the office copy of the FOM; I grab his arm and asked him where his was (I knew his was in the back window of his car, where anyone could see it -including our POI who was on premises that day). I direct him to go get his, and he first stammers that he doesnt know, I splain that I saw his in the back seat of his car plainly in the back window; and that he better get it pronto.
Taking a desk over from this individual was like playing you bet your license; and on several occasions I refused to take a flight or two over until they landed for their releases weren't legal (bad alternates, no alternates, you get the picture).
A lot of it is, especially in the regional world, that real training is nonexistent. They get kids fresh out of school with a tempo ticket (and those kids barely know 121), who hardly know their ass from a hole in the ground, and couldnt dispatch on a VFR day to save their soul.
I put a lot of the failure onto the schools themselves, and the whole dispatch training methodologies; in what other FAA certificated position do you not do the job to get the certificate; a pilot goes and flies an airplane, I assume a mechanic goes and puts an engine together or something (I dont know for sure what a mech's practical is), a dispatcher chases a manual flight plan through such a cumbersome process that if an airline did it that way, nothing would ever leave the ground. There is no "practical application" of what dispatching really means; and that doing the tap-tap-send stuff is the easy part.
Dispatcher certification is so unreal and un-real-world that, combined with the lackadaisical training in the regional world (at least most, but not all) is the perfect storm; low certification standards combined with a low comp check standard (breathing, good, you pass), and with crap pay means you get what you pay for.
I take pride in any release with my name on it, but I must be in the minority.
