My new policy on missed class sessions, late work, and extensions

My policy on missed class sessions, late work, and extensions is modeled after the vacation, personal, and sick day policies common in many workplaces. Holidays and vacation days are built into the semester’s schedule (e.g., Labor Day, Fall Break, Thanksgiving Break). Students have a combination of three additional personal/sick days in this class. Any personal/sick day may be used for a one-day extension on an assignment. Late assignments are otherwise docked 10% per day. One of these personal/sick days may be used to excuse an absence. (Given that this class meets only once per week, only one absence may be excused.)
