K.S.
I would think it is your responsibility to ask the questions not have them be the one telling you everything. Many parents may not care about this, so therefore they may not volunteer information. I wouldn't be so quick to be dissapointed. The state did say that they haven't got their license yet, not that it was denied. I think you may be reading too much into this.
I would see about working something out with your job. If they will go for it, then that would be what's best for your kids, then you won't have to worry.
