Since when have people worked in same place for all their life? First you teach in one place, then you get a job in other, then you get back to teaching in the place you were before. Why do we need an explanation more complicated than that?
Also, Indy had his own study (and TA) in LC. Is that usual for professors who are just visiting?
And oh yeah, he was still at Barnett in FoA (which takes place a year after LC and is very much canon). So much for "visiting professor" theory.
Good point on his office and the TA, and, I suppose, for FoA, as entirely slipped my mind during my initial post that Barnett was the college in the game.
I suppose one thing that has slipped my mind lately in a number of posts about how Indy isn't the model professor, since he's constantly traveling around the world at a moment's notice, is that he is apparently world-renowned, with Chatter Lal being the most obvious example of this. Taking this in mind, Dr. Jones would be quite a get as a rock star professor, and Barnett conceivably was able to make Indy an offer that he found appealing, including a huge office.
FoA places Barnett as somewhere near Syracuse, New York (

And hence re-enters Marshall College, conveniently located in Connecticut and eager to rehire a professor with some star power, despite occasional dereliction of his duty.
