Short-term job (3)
I believe the answer is:
gig
'short-term job' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gig that I've seen before include "One-night stand" , "A booking for musicians" , "In pop parlance, a one-night performance" , "A one-night musical engagement" , "Horse carriage - performer's single booking" .)
