Rebellious press employee in extreme situation (13)
I believe the answer is:
insubordinate
'rebellious' is the definition.
(similar in meaning)
'press employee in extreme situation' is the wordplay.
I cannot quite understand how this works, but
'in' is found in the answer.
'press employee' could be 'sub' (subeditor) and 'sub' is found in the answer.
The remaining letters 'ordinate' 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).
(Other definitions for insubordinate that I've seen before include "Defiant of authority" , "challenging authority" , "Insolent" , "Badly behaved" , "Rebellious" .)
