A job is at stake (4)
I believe the answer is:
post
This could be a double definition.
'a job' is the first definition.
(I know that post is a type of job)
'at stake' is the second definition.
'post' can be an answer for 'stake' (synonyms). I'm unsure of the 'at' bit.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for post that I've seen before include "delivery" , "Leave message online" , "Mail; office" , "Contribute online" , "(Holiday) communication" .)
