Insecure sort of job many want (8)
I believe the answer is:
sinecure
'job many want' is the definition.
(term for a well-paying but undemanding job)
'insecure sort' is the wordplay.
'sort' indicates anagramming the letters.
'insecure' anagrammed gives 'SINECURE'.
'of' acts as a link.
(Other definitions for sinecure that I've seen before include "Soft job, may be insecure" , "Paid job with minimal work - insecure (anag)" , "Undemanding job" , "An office without work." , "Job for easy money" .)
