Silent after vacation with a very loud man (5)
I believe the answer is:
staff
'man' is the definition.
(both can mean to work at a particular post)
'silent after vacation with a very loud' is the wordplay.
'after vacation' means to remove the middle letters (the inside letters must vacate).
'with' means one lot of letters go next to another.
'very loud' becomes 'ff' (musical abbreviation).
'silent' with its centre taken out is 'st'.
'st'+'a'+'ff'='STAFF'
(Other definitions for staff that I've seen before include "Administrative personnel" , "support for notes" , "Rod; workers" , "Administrators etc - stick" , "Rod - workforce" .)
