In the morning, if in work, will get raise (7)
I believe the answer is:
amplify
'raise' is the definition.
(thesaurus)
'in the morning if in work' is the wordplay.
'in the morning' becomes 'am'.
'in' is an insertion indicator.
'work' becomes 'ply' (I've seen this before**).
'if' placed inside 'ply' is 'plify'.
'am'+'plify'='AMPLIFY'
'will get' acts as a link.
(Other definitions for amplify that I've seen before include "Make louder or fuller" , "Increase in size, volume or significance" , "Make (signal) bigger" , "Increase (a signal)" , "Add strength or details to" .)
