Charity of sorts protecting jobs (10)
I believe the answer is:
kindliness
'charity' is the definition.
(thesaurus)
'sorts protecting jobs' is the wordplay.
'sorts' becomes 'kinds' ('kind' can be a synonym of 'sort').
'protecting' is an insertion indicator (inserted letters are held or protected).
'jobs' becomes 'lines' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'kinds' enclosing 'lines' is 'KINDLINESS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for kindliness that I've seen before include "Friendly and considerate manner" , "Benevolent and helpful nature" , "Friendliness, consideration" .)
