Hate working at hole (6)
I believe the answer is:
loathe
'hate' is the definition.
(I know this)
'working at hole' is the wordplay.
'working' indicates anagramming the letters.
'at'+'hole'='athole'
'athole' anagrammed gives 'LOATHE'.
(Other definitions for loathe that I've seen before include "Dislike intensely" , "Find disgusting" , "Feel intense dislike or disgust for" , "Feel strong disgust for" , "Strongly detest" .)
