From what i can tell, this song is supposed to be played with a capo on the first fret, 
my guitar teacher is always saying that capos are for people who can't play bar chords, 
i i figured it out with bar chords instead. so here goes, hope this sounds right...

Ab
intro, spoken:
I dedicate this song to the workin' man
For ever' man that puts in a hard
Eight or ten hours a day of work and toil and sweat
Always got somebody lookin' down his neck
Tryin' to get more out of 'im
Than he really ought to have to put in.

 Ab
After twenty nine long years

of workin' in this shop
                        Bb7
with Oney standing over me
Eb7
Today when that old whistle blows,
                                       Ab
I'll check in all my gear, and I'll retire.
 Ab
The superintendant just stopped by
                                      Bb7
and said they planned my little get-together
Eb7
and then he said I'd never have made it
                                     Ab
if old Oney hadn't of held me to the fire

 Ab
I've seen him in my dreams at night
                                    Bb7
and woke up in the morning feeling tired.
          Eb7
And old Oney don't remember, when i came here,
                         Ab
how he tried to get me fired...
 Ab
With his folded hands behind him,
                                   Bb7
every morning, Oney waited at the gate...
           Eb7
where he'd rant and rave like i committed murder
                          Ab
clockin' in five minutes late.

Bb
But today they'll gather 'round me
                                    B#7
like I've seen 'em do when any man retires,
         F7
and old Oney's gonna tell me,
                                    Bb
from now on, I'm free to do what i desire.
Bb
He'll present me with that little old gold watch
                             B#7
they give a man a times like this,
            F7
but there's one thing he's not countin' on...
                                Bb
today's the day i give old Oney his! hahahahaha!

C#
I've been workin' buildin' muscles,
                                              Bb7
Oney's just been standin' 'round, and gettin' soft,
     Ab7
and today about 4:30, I'll make up for every
                         C#
good night's sleep I've lost...
 C#
When I'm gone, I'll be remembered
                                      Bb7
as the workin' man that put his point across...
       Ab7
With a right hand full of knuckles,

today's the day I show old Oney
          C#
who's the boss!

(just keep strumming C#)
Hmmmmmmm, what time is it? 4:30? Heeeeeyyyy Oney! Oney! haha!
