America has time for employment (5)
I believe the answer is:
usage
'for employment' is the definition.
(synonyms)
'america has time' is the wordplay.
'america' becomes 'US' (United States).
'has' says to put letters next to each other.
'time' becomes 'age' (an age is a period of time).
'us'+'age'='USAGE'
(Other definitions for usage that I've seen before include "Terminology - custom" , "Treatment, practice" , "Custom - treatment" , "Customary practice" , "Habitual custom" .)
