Hiring is nice without leader (7)
I believe the answer is:
leasing
'hiring' is the definition.
('lease' can be a synonym of 'hire')
'nice without leader' is the wordplay.
'nice' becomes 'pleasing' (I've seen this in another clue).
'without leader' means to remove the first letter.
'pleasing' with its initial letter taken off is 'LEASING'.
'is' is the link.
(Other definitions for leasing that I've seen before include "Renting" , "A single (anag.)" , "Financial arrangement" , "Chartering" , "Letting for money" .)
