In Leeds I arranged a second job (8)
I believe the answer is:
sideline
'a second job' is the definition.
(I've seen this before)
'in leeds i arranged' is the wordplay.
'arranged' indicates an anagram.
'in'+'leeds'+'i'='inleedsi'
'inleedsi' with letters rearranged gives 'SIDELINE'.
(Other definitions for sideline that I've seen before include "second job" , "Prevent from participating" , "Spare-time activity" , "Secondary activity" , "hobby" .)
