Steady sort of job for a lad (6)
I believe the answer is:
stable
'steady' is the definition.
(associated in meaning)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for stable that I've seen before include "Lasting" , "Products all from same place" , "farm building" , "Well-balanced and steady" , "Horse barn" .)
