Disagree with an attitude taken at work? (6)
I believe the answer is:
oppose
'disagree with' is the definition.
(thesaurus)
'an attitude taken at work?' is the wordplay.
I cannot really see how this works, but
'attitude' could be 'pose' (attitude can mean a pose or stance) and 'pose' is found within the answer.
'work?' could be 'op' (common abbreviation for 'opus') and 'op' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oppose that I've seen before include "Argue against" , "face" , "Act against" , "Resist, go against" , "Resist or fight against" .)
