It might be consulting the first chapters of 'The Long Weekend- 'The Living Story of the Twenties and Thirties' by Robert Graves & Alan Hodges, has some interesting material about unemployment amongst former servicemen, especially former officers.
'We Will Remember Them-Voices from the Aftermath of the Great War' by Max Arthur , has some fascinating recollections from those who returned.
On a more general note there were disturbances in Liverpool and Glasgow in 1919, but whether these were due to increased militancy amongst the workers who did not fight , or involved de-mobbed service people, I am not sure.
Personally I find 1919 one of the many fascinating topics resulting from the political consequences of the Great War.
