It's fashionable to be absorbed by safe cushy job (8)
I believe the answer is:
sinecure
'cushy job' is the definition.
(I've seen this before)
'it's fashionable to be absorbed by safe' is the wordplay.
'it's fashionable' becomes 'in' ('in' can be similar in meaning to 'fashionable').
'to be absorbed by' means one lot of letters goes inside another.
'safe' becomes 'secure' ('secure' can be a synonym of 'safe').
'in' put into 'secure' is 'SINECURE'.
(Other definitions for sinecure that I've seen before include "Office that involves minimal duties" , "Insecure in cushy job" , "Soft job, may be insecure" , "Post requiring little work" , "Paid job with minimal work - insecure (anag)" .)
