As the others said this is far from ideal situation.
A puppy needs company and care so that it grows up well adjusted and happy.
Ideally you would provide this, but working full time means you can't. There are alternatives. From your writing style I guess you are in USA or Canada. On the breed email lists I am on I notice that Doggy Daycare is something that exists over there, and know a few working list members that use this option.
I would expect that option may be more than many people can afford.
Have you an older neighbour who likes dogs that would enjoy having her company in the daytime, or would be prepared to come in twice a day for an hour or so fat a time for a small amount of money.
Your Vet may know of someone who doesn't feel able to have the responsibility of a new dog due to their age, but would love to share one.
If none of this is possible I would take her to work in a crate, taking her out for regular toilet breaks and for a game during your lunch hour.
I would not let the children over face her, as unfortunately children tend to treat puppies like animated toys, and can scare or hurt them. Also due to their small size they keep wanting to pick them up which as they get molder they are les and less likely to appreciate. As long as her associations with the children are pleasant she will be OK, but they shoulde be kept short and not too many kids at a time.
Also puppies need their rest, and if overtired c an become grumpy and bitey.
