News — it is interrupted by Scottish strike (7)

I believe the answer is:
tidings
'news' is the definition.
(synonyms)
'it is interrupted by scottish strike' is the wordplay.
'it is' becomes ''tis' ('tis' is short for 'it is').
'interrupted by' indicates putting letters inside.
'scottish strike' becomes 'ding' (I can't explain this - if you can you should give a lot more credence to this answer).
'tis' placed around 'ding' is 'TIDINGS'.
Can you help me to learn more?
(Other definitions for tidings that I've seen before include "News (obs.)" , "News, information" , "Information about recent events" , "News (arch.)" , "News, reports" .)
