Get worker to accommodate committee (6)
I believe the answer is:
become
'get' is the definition.
('become' can be a synonym of 'get')
'worker to accommodate committee' is the wordplay.
'worker' becomes 'bee' (I've seen this before).
'to accommodate' is an insertion indicator.
'committee' becomes 'com' (abbreviation for committee).
'bee' enclosing 'com' is 'BECOME'.
(Other definitions for become that I've seen before include "Suit, befit" , "Change into - suit" , "Suit; turn into" , "Flatter" , "Develop into something" .)
