Happy Labor Day everyone! That is, those of you who have the day off... have job to be taking the day off from... and so forth. But just be thankful that you didn't work in the Middle Ages -- although after reading this, maybe you'll wish you were.

10. Jimmy Hoffa

James R. Hoffa is not buried under Giants Stadium (or what was used to be Giants Stadium.) The groundbreaking and ultimately corrupt leader of the International Brotherhood of the Teamsters was "disappeared," probably by other mobsters, in 1975 and declared deceased after having been missing for seven years. His body has never been found, although speculation has run rampant ever since; a 1976 FBI memo theorizes that the Mafia wanted him dead in case he discovered they were skimming from a union pension fund.

Hoffa was pursued by then-Attorney General Robert F. Kennedy up until Hoffa's 1964 for bribing a grand juror. He retained his title of President throughout his four years in prison, upon which time he was pardoned by President Nixon. The terms of the deal prevented him from being involved in union activity until 1980... but he never made it that long. Or has he?

9. The Wisconsin Recall Fight

Republican Governor Scott Walker and Republican legislators came under fire for passing a bill that stripped state workers of collective bargaining rights. When Walker was caught on tape discussing his plan to destroy unions with an activist posing as one of the Koch brothers, a powerful pair of billionaires who make no bones about their efforts to crush employee wages for their own benefit, Wisconsinites were outraged and demanded a recall of elected Republicans.

But the recall election fell short: Democrats needed three pickups to take over the State Senate and, presumably, reverse the law, but they fell short on new seats. The law also survived a court fight that first saw it overturned. Its ramifications are not yet known, but other states are looking to adopt similar bills to weaken the worker's power.
