Meek Mill is seriously cleaning up while he's in prison, bouncing between several different jobs ... and doing it at a rate light-years from his rap dough.
Meek's serving his 2 to 4 years at Pennsylvania's SCI Chester ... where he's part of the general labor crew, getting his hands very dirty. A prison rep tells us Meek cleans the cell block, tidies up prison grounds and washes dishes. He also cooks food and serves it up, too!
This is the definition of being humble. We talking about an artist who makes way more then nineteen cent a hour. He's locked up serving his time and working just like anybody else would.
