Line up again for compensation (7)
I believe the answer is:
redress
I believe this is a double definition.
'line up again' is the first definition.
('dress' can be a synonym for 'line up' so perhaps 'redress' is OK for 'line up again')
'compensation' is the second definition.
(redress is a kind of compensation)
'for' is the link.
(Other definitions for redress that I've seen before include "Prepare again - satisfaction" , "Make amends for" , "Reparation" , "relief" , "Set right - compensation" .)
