Smillette -
I know it is hard to be a single parent with kids, DH & I don't have DSS at our house all the time and their are two of us, we still juggle with work schedules, school schedules, day care, etc. I hope your friend can find a resource - there are single parent support groups that spring up on places like MeetUp or Craigs list in some areas, though use caution with anyone you find like that. Like Julie, I don't agree that it is the schools responsibility to take care of this situation, but like you, I feel like the school should be a resource. When I was in high school I drove two kids to band practice and back every day with me - their mom called the school and asked for help, said her kids would have to drop out if their wasn't someone who could drive them. My band director found me and asked me to help out. We wouldn't have had that link without him. Try the kids teachers, they may know some parents who could help. It is sad to me that the school system can't recommend a daycare center out of worries of liability...
Like some people have said, daycare centers often will transport kids to school - that is why I was asking the ages. DSS's daycare buses to the elementary schools, but not the middle or high school. They let you drop off as early as 6:30 then they handle the school transport, both to and from school actually - they will pick them up and bring them back to the daycare for pickup by 6:30 pm.
Jobs are starting earlier and ending later more and more these days, DH's ex has had 12 hour shifts in the past, now she starts at 7 am. In the past when she had to go to work before the daycare opened DH would go pick up DSS and take him to daycare when it opened. I know that they are divorced, but could the mother be a resource to help out on these two days? Non traditional I know, but DH & his ex have had some success with this kind of cooperation.
Good luck to him.
ETA - has he asked about flex hours during the rest of the week to make up for the time on Monday & Tuesday? I figure he has to get out early those days as well to pick them up? Moms get flex hours a lot faster than Dads, but it has been known to happen.
