Think constantly about retaining jobs, essentially (6)
I believe the answer is:
obsess
'think constantly about retaining jobs essentially' is the definition.
I can't judge whether this definition defines the answer.
'about retaining jobs essentially' is the wordplay.
'about' says the answer is hidden in the clue.
'OBSESS' is hidden within 'retaining jobs essentially'.
Can you help me to learn more?
(Other definitions for obsess that I've seen before include "Haunt - preoccupy" , "Be constantly talking about" , "Plague" , "Prey on" , "Be constantly preoccupied" .)
