Workers initially undercharged for fare (4)

I believe the answer is:

'fare' is the definition.
(menu is a kind of fare)

'workers initially undercharged' is the wordplay.
'workers' becomes 'men' (man is a kind of worker).
'initially' suggests taking the first letters.
The first letter of 'undercharged' is 'u'.
'men'+'u'='MENU'

'for' is the link.

(Other definitions for menu that I've seen before include "Carte du jour" , "that can appear on computer screen" , "List of items available in restaurant (4)" , "Bill of fare" , "Food programme of restaurant" .)

I've seen this clue in The Telegraph.
