A few sexual terms(no more than three) are discreetly used as slang to describe non-sexual situations(ie "this is not "jerk-off time")

We see some documentary images inside the Hormel meatpacking plant that shows pigs briefly being prodded by possible electric prongs, pig carcasses being cut up(once by a buzzsaw from a discreet angle), faces hanging off pigs, a little blood, and briefly some organs seen briefly but clearly from a slight distance. These images are not particularly graphic but they might disturb some viewers.

We see some protesters throw rocks and bricks at cars and trucks briefly.

Some pushing and shoving in a crowd at a union meeting that results with some people on the floor.

Police forcibly remove and arrest some picketers.

2 uses of f**k. The following is an estimate that is close and sometimes accurate: about 12 uses of goddamn, 11 uses of s**t, 12 uses of hell, 4 uses of ass, 3 uses of asshole, 2 uses of dick(once as an insult; once for male genitals), 3 uses of piss, 1 use of bastards, and 8 uses of damn.

Some cigarette smoking.

Lots of angry yelling and a brief intense scene involving the National Guard but it doesn't result in any violence.
