Hoffa did alot of good things for the Union Workers back then in which established negotiations practices that we use today, yeah he was taken out cause he wouldn't give out on the pension fund but remember this he knew when he first associated with the Boys that that could happen! It's the life like Jimmy says!
No that was based on The second book The "irishman" had written about his live. He wrote two biographies but his real one sold bad so he made a fictional one that sold good, and this one is what The movie is based on.
