Laugh in front of employment building (5)
I believe the answer is:
house
'building' is the definition.
(I know that house is a type of building)
'laugh in front of employment' is the wordplay.
'laugh' becomes 'ho' (representation of a laughing sound).
'in front of' is a charade indicator (letters next to each other) (some letters go in front of others).
'employment' becomes 'use' (how something is used).
'ho'+'use'='HOUSE'
(Other definitions for house that I've seen before include "See 1" , "Inn" , "Dwelling; dynasty" , "Royal family" , "Company; dwelling" .)
