I don't have this issue since I don't have teens but I went to a different HS then my older brother, his was a selctive HS and a fair distance from home, mine was a local HS. Both my parents worked but my dad was usually home by about 4:30, 5 at the latest. At first I would go to my next door neighbours house but after a couple of weeks we all decided I would just go home and spend that time doing homework. I was only ever allowed one friend over and my neighbours had to be told. I enjoyed this time by myself.

Do you have neighbours you could trust and talk to?

Otherwise are there any after school care places around.
