Post Office; a novel.
(Book)

By middle age, Henry Chinaski has lost more than twelve years of his life to the U.S. Postal Service. In a world where his three true, bitter pleasures are women, booze, and racetrack betting, he somehow drags his hangover out of bed every morning to lug waterlogged mailbags up mud-soaked mountains, outsmart vicious guard dogs, and pray to survive the day-to-day trials of sadistic bosses and certifiable co-workers.
