One missing a work meeting told to go inside (8)
I believe the answer is:
absentee
'one missing' is the definition.
(someone who is absent)
'a work meeting told to go inside' is the wordplay.
'work meeting' becomes 'bee' (I've seen this in other clues).
'told to go' becomes 'sent' (sent away).
'inside' is an insertion indicator.
'bee' enclosing 'sent' is 'bsentee'.
'a'+'bsentee'='ABSENTEE'
(Other definitions for absentee that I've seen before include "to be called in? No!" , "skiver" , "One failing to attend" , "Bunker" , "One who should be but isn't present" .)
