Post Office by Charles Bukowski

Charles Bukowski's classic roman à clef, Post Office, captures the despair, drudgery, and happy dissolution of his alter ego, Henry Chinaski, as he enters middle age.
Post Office is an account of Bukowski alter-ego Henry Chinaski. It covers the period of Chinaski's life from the mid-1950s to his resignation from the United States Postal Service in 1969, interrupted only by a brief hiatus during which he supported himself by gambling at horse races.
