Those were eight hour days right? We worked an eight hour, three shift per day schedule for a while before the current 12hr schedule.
Eight hour shifts, yes - the plant ran 24/7/365 and holidays worked were double time and a half. Anything over 8 hours the employer was required to provide a meal (roach coach). United Steelworkers Union, IIRC. It was good money at the time, 11 or 12 bucks an hour.
