Be noted as an industrious worker (3)
I believe the answer is:
bee
'worker' is the definition.
(a worker bee)
'be noted as an industrious' is the wordplay.
I cannot quite understand how this works, but
'be' is within the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bee that I've seen before include "Apian insect" , "queen, perhaps" , "Hairy-bodied insect" , "Creator of honey" , "Honey-making insect" .)
