Michael, I know you where right in the 80’s. When stationed in Korea, that was the only time I worked a day shift. State side at Wright Patterson and Fort Meade I worked nights. The civilians got a 10 percent night differential. So to save money they had all us Military work those shifts. Even then there where still 5 civilians to do 1 job. I worked (by choice) while they bitched and played cards in the break room. So, yes there was an issue in the 80’s. But I do not know if it is the same today. I wouldn’t doubt it though.
