Run risks with time slippage in job requiring Russian cash (3,3,7)
I believe the answer is:
ask for trouble
'run risks' is the definition.
'with time slippage in job requiring russian cash' is the wordplay.
'with' is an insertion indicator.
'time' becomes 't' (abbreviation).
'slippage in job' becomes 'askfor' (I can't justify this - if you can you should believe this answer much more).
'requiring' says to put letters next to each other.
'russian cash' becomes 'rouble'.
'askfor'+'rouble'='askforrouble'
't' put within 'askforrouble' is 'ASK FOR TROUBLE'.
(Other definitions for ask for trouble that I've seen before include "expose oneself to difficulties" , "Act in a way likely to incur difficulties" , "Provoke retaliation" , "Invite difficulty by one's actions" , "Behave provocatively" .)
