I lost my job in 1972 in the wake of the R_R debacle. We were not sub contractors to R-R, but a lot of people we subcontracted to were. They went bust as their bills were not paid. We lost several irreplaceable sources of highly specialised engineering and we eventually went bust as well as we could not fulfil our contracts. Watch for the ripples of this Carillion collapse as they spread through the little firms, who worked for the bigger firms, who worked for Carillion. This is going to be a bloodbath.
