My sister has a degree in elementary education. Because she lives in a college town that churns out education majors in a dying state in the Midwest, it took her a few years to find a teaching job. In the meantime, she clocked some serious hours as the director of a before- and after-school program. On days like Martin Luther King, Jr. Day, the regular teachers had the day off. Dana had to be at work at 6 am. The parents who used the program needed to send their kids to school while they worked. Schools may be closed, as are banks and the government, but increasingly people are working in jobs that don’t observe federal holidays or give it to workers as a paid day.
