Retirement benefit: former workers getting hour tucking into a keg, drunk (6,9)

I believe the answer is:
golden handshake
'retirement benefit' is the definition.
Both the answer and definition are singular nouns.
Maybe there's a link between them I don't understand?
'former workers getting hour tucking into a keg drunk' is the wordplay.
I cannot quite see how this works, but
'former' could be 'olden' (I've seen this before) and 'olden' is found within the answer.
'workers' could be 'hands' (hand is a kind of worker) and 'hands' is located in the answer.
'hour' could be 'h' (abbreviation) and 'h' is found within the answer.
'a' is found in the answer.
an anagram of 'keg' is 'gke' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for golden handshake that I've seen before include "Improved P45" , "Ready to remove" , "this may be hoped for on retirement!" , "Parting gesture" , "Reward for retiring" .)
