Time to move into light work (3,5)
I believe the answer is:
day shift
'time' is the definition.
(thesaurus)
'move into light work' is the wordplay.
I cannot really understand how this works, but
'move' could be 'shift' (shifting is a kind of moving) and 'shift' is found in the answer.
'light' could be 'day' (I've seen this in other clues) and 'day' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Another definition for day shift that I've seen is " Relay of workers".)
