Have any of you ever subbed for extra money? Is it worth it? I'm thinking of putting my name on the list (for the whole local school system: K-12) since it will be the hours my oldest 3 are in school and I will only have 1 to leave at my grandma's or my aunt's. Does this sound like a viable plan? Also, I was thinking it might get my "foot in the door" toward getting a teacher's aide or other job for the school next fall. It's hard to get hired on at the school here . . .
