Theatre worker put on by husband also (9)
I believe the answer is:
stagehand
'theatre worker' is the definition.
(I've seen this before)
'put on by husband also' is the wordplay.
'put on' becomes 'stage' (to put on a show is to present or stage it).
'by' says to put letters next to each other.
'husband' becomes 'h'.
'also' becomes 'and' (both can mean in addition).
'stage'+'h'+'and'='STAGEHAND'
(Other definitions for stagehand that I've seen before include "Scenery/props person" , "General helper for play, moves scenery etc" , "One may move flats" , "Eg, sceneshifter" , "Theatrical props handler" .)
