Today, people who have remedial jobs like that,
I think you mean "menial". O'Brien doesn't strike me as needing to have education repeated because he didn't get it the first time.
And as I said in the thread about the comic, I imagine O'Brien has more responsibilities than we see. Completely aside from the imagined duties I added to him over there, we know he oversees maintaining and calibrating the transporters because he mentioned it on a couple of occasions, even if we never/rarely saw him doing it.
But, I imagine he still finds time to sneak in his love of Eugenics War-era movies and tv shows, stuff like "Get Him To The Greek", "Stargate: Atlantis", and "The Magical Legend of the Leprechauns".
