At your suggestion I only studied the links for the less academic (after all I cannot aspire to the exulted heights of Technical Services). Anyway I found the info rather frightening as I worked night shift for many years.
While I agree that the results are quite conclusive. I feel that some fault for the health problems in your work area must be the result of spending too many years working for a mis-managed company, that through lack of firm direction from the top, forces it's staff into a state of perpetual stress.
I have had some contact with your company and as another link on this site shows, it is surprising that any of the staff are still healthy and happy.
Thank you for some interesting reading.
