At home, occupying safe and cushy position (8)
I believe the answer is:
sinecure
'cushy position' is the definition.
(I've seen this in another clue)
'at home occupying safe' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'occupying' indicates putting letters inside (inserted letters occupy or enter the word).
'safe' becomes 'secure' (synonyms).
'in' going inside 'secure' is 'SINECURE'.
'and' is the link.
(Other definitions for sinecure that I've seen before include "Informally, a bobby's job" , "Insecure in easy job" , "Paid job involving little or no work" , "Job for easy money" , "An office without work." .)
