Jobs for the boys — as postmen, I suspect (8)
I believe the answer is:
nepotism
'jobs for the boys' is the definition.
(term for giving jobs to one's family or friends)
'postmen i suspect' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'postmen'+'i'='postmeni'
'postmeni' anagrammed gives 'NEPOTISM'.
'as' acts as a link.
(Other definitions for nepotism that I've seen before include "keeping it in the family" , "The practice of favouring one's relatives in making official appointments" , "Pimentos (anag.)" , "Taking on family" , "Jobs for the boys" .)
