'casual work's' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'grim round any heartless scientific workshop?' is the wordplay.
'grim' becomes 'dour' (synonyms).
'round' means one lot of letters goes inside another.
'heartless' means to remove the middle letters.
'scientific workshop?' becomes 'lab' (laboratory. I am not sure about the 'scientific' bit.).
'any' with its middle removed is 'ay'.
'ay'+'lab'='aylab'
'dour' enclosing 'aylab' is 'DAY-LABOUR'.
