Nervous when there’s wages about to steal (7)
I believe the answer is:
panicky
'nervous' is the definition.
(thesaurus)
'wages about to steal' is the wordplay.
'wages' becomes 'pay' (I've seen this before).
'about' means one lot of letters goes inside another.
'to steal' becomes 'nick' (I've seen this before).
'pay' placed around 'nick' is 'PANICKY'.
'when there's' acts as a link.
(Other definitions for panicky that I've seen before include "nervous!" , "(Irrationally) fearful" , "Dreadfully anxious" , "Inclined to lose head" , "Suffering fear, anxiety" .)
