One time, one of my coworkers showed up to work with his kid, because the babysitter called in sick. My manager, without skipping a beat, told him to go home and be the best dad he possibly could, then, not only did she not use his sick time for this day, she made it a department policy to allow unlimited* "parent days". One of the best managers I've ever had.
' * Fine print was basically, don't abuse it, but use it when you need it.
