Resignation poem

Dear Sir,

I left the mob
to join your job
but realized then
I was just a pecked hen
you were too harsh
threw my best effort into the trash
you looked scary
mustachioed and fiery
I actually shivered
and somewhat quivered
when you bellowed
I grew mellowed
I waited for years
cheeks overflowing with tears
my career bent 
you didn't repent
my promotion wasn't sent
I said enough's enough
amidst my racking cough
so I'm going
decision not regretting
here I don't have a life
am leaving with your wife!
