Withdraw from dire pub job in the end (3)
I believe the answer is:
ebb
'withdraw' is the definition.
(I've seen this in another clue)
'dire pub job in the end' is the wordplay.
'in the end' says to take the final letters.
The final letters of 'dire pub job' are 'EBB'.
'from' acts as a link.
(Other definitions for ebb that I've seen before include "Not to wax" , "Go out or recede like tide" , "Drain away; decline" , "Outward flow of the tide" , "Flow back or recede" .)
