''One who avoids work being performed'' is about right (5)
I believe the answer is:
drone
''one who avoids work' is the definition.
I can't judge whether this defines the answer.
'performed' is about right' is the wordplay.
'performed'' becomes 'done' (done can mean performed or accomplished).
'is about' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'done' placed around 'r' is 'DRONE'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for drone that I've seen before include "person averse to work" , "mollusc" , "Unmanned aircraft" , "Low hum; parasite" , "Hum; monotonous talk" .)
