Rather than bending early birds and night owls to the same workschedule, why not encourage personalized schedules based on each individual's circadian rhythms?
For example, their workschedule which implied either opening a community radio station as early as 4am or closing it late at night exposed them to dangers on deserted streets.
Recognizing this helped me set a better schedule: Now, I work late instead of coming in early, and I can usually pack much more productivity into my day.
