Does nothing, largely being paid less (5)
I believe the answer is:
idles
'does nothing' is the definition.
(I've seen this before)
'largely being paid less' is the wordplay.
'largely' indicates the answer is hidden within the clue.
'IDLES' can be found hidden inside 'being paid less'.
(Other definitions for idles that I've seen before include "Does little, just ticks over" , "Wastes time" , "Lazes about, just ticks over" , "Lazes around" , "Spends time doing nothing" .)
