Leaving job, being shy (8)
I believe the answer is:
retiring
'shy' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for retiring that I've seen before include "Bashful" , "Giving up work for good" , "Giving up work permanently" , "Timid" , "of unobtrusive aspect" .)
