It’s about weary workers facing end of employment (10)
I believe the answer is:
retirement
'end of employment' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'it's about weary workers facing' is the wordplay.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'about' is a charade indicator (letters next to each other).
'weary' becomes 'retire' (retiring is a kind of wearying).
'workers' becomes 'men' (men can mean staff or employees).
'facing' means one lot of letters go next to another.
'retire'+'men'='retiremen'
't' put after 'retiremen' is 'RETIREMENT'.
Can you help me to learn more?
(Other definitions for retirement that I've seen before include "period as emeritus?" , "Withdrawal" , "Time without any work being done" , "Life after work" , "Going to bed? - I met renter (anag)" .)
