You would think she'd want to finally have a more relaxed routine summer mornings, but maybe her child is a super early riser; but then it's a good time to spend some no rush time with her kid.... I personally would not open earier as an exception during the summer... She can be the one to adjust to your schedule during this time. You're very generous to open early just for her the rest of the year. Children do attend with me on PA days. I work 8 to 5, no exception and I have teachers. It's my protection against burn out and ensures I'm fresh and happy for their children each day. During interview I tell them that.
