Skilful plan eliminating staff work (6)
I believe the answer is:
oeuvre
'work' is the definition.
(an oeuvre is someone's collected works)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for oeuvre that I've seen before include "Body of artistic or literary work" , "(Artist's) body of work" , "(Artist's) collected work" , "Artist's total output" , "Body of work of an artist (6)" .)
