The position is bad: treacherous conditions underfoot (6)
I believe the answer is:
office
'the position' is the definition.
(synonyms)
'bad treacherous conditions underfoot' is the wordplay.
I cannot really see how this works, but
'bad' could be 'off' (eg meat that's gone off is bad) and 'off' is present in the answer.
The remaining letters 'ice' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for office that I've seen before include "Where many of us work" , "Business room - position of responsibility or duty" , "Box ---, ticket agency" , "Workplace for white-collar workers" , "Position in government?" .)
