Ah yes, the Teamsters.
That's a good point DC.
There's an older book that should still be around "Mobbed Up" by James Neff which details the life and times of Jackie Presser, the Teamsters, the transition of the Cleveland Mob from Jewish to Italian, and the links between the various mob groups, Las Vegas casinos/hotels and the Teamsters Union.
It's dry reading but full of lots of facts.
Good book, Lilo. There was also a tv movie made about Presser in the early '90s, starring Brian Dennehy as Presser. For tv fare, it wasn't bad.
