Former employee's game? (3,4)

I believe the answer is:

old maid

'game?' is the definition.
(I've seen this before)

'former employee's' is the wordplay.
'former' becomes 'old' (both can mean previous).
'employee' becomes 'maid' (I've seen this before).
'old'+'maid'='OLD MAID'

(Other definitions for old maid that I've seen before include "game of cards" , "Fusspot; card game" , "Singleton" , "Miss" , "never taken from the shelf?" .)

I've seen this clue in the Evening Standard.
