Song from worker on edge (6)
I believe the answer is:
anthem
'song' is the definition.
(anthem is a kind of song)
'worker on edge' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'on' says to put letters next to each other.
'edge' becomes 'hem' (I've seen this before**).
'ant'+'hem'='ANTHEM'
'from' acts as a link.
(Other definitions for anthem that I've seen before include "The man for a rousing song" , "National melody" , "National or church song" , "air of patriotism?" , "Church choral piece" .)
