Hypothetical argument about skills with worker (5,3)
I believe the answer is:
straw man
'hypothetical argument' is the definition.
(term for a misrepresentation of an argument)
'about skills with worker' is the wordplay.
'about' shows that the letters should be reversed in order.
'skills' becomes 'arts' (art can mean a skill or talent).
'with' becomes 'w' (abbreviation).
'worker' becomes 'man' (man is a kind of worker).
'arts' back-to-front is 'stra'.
'stra'+'w'+'man'='STRAW MAN'
(Other definitions for straw man that I've seen before include "Argument put forward to stimulate discussion" , "Aunt Sally" , "Person who is a sham" , "Figure without substance" , "One lacking substance" .)
