Low-paid laborer
I believe the answer is:
peon
'low-paid laborer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for peon that I've seen before include "Day-labourer" , "Spanish-American menial worker" , "Spanish-American farm labourer" , "A Mexican peasant or labourer" , "Spanish-American farm worker" .)
