Cool. Happy to see you're focused on other verticals that would be willing to pay. I see it every day with my friends. Manager sends out PDF of schedule, giant white board in back office, calls to manager on day of shift to reschedule. Manual optimization to cover the over / under problems. Plus the laws. As an engineer I was screaming but never could figure out how to make the business a good sell over their entrenched ways and existing ways of tracking.
