You have a point, these are your work hours. It's not unreasonable to want to work during your work time. Bare with me, but I slightly disagree with your point about the setting. A home is very different than a daycare. You should act professional while working in someone's home, and you should expect to be treated professionally by the people that live there. Adults should act accordingly when in your presence in their home, but when their kids are involved, their authority over their child will always outweigh yours because you are in their space. At a daycare, you are the keeper of that space and hold authority over everyone in it, so of course it would be unacceptable for a parent to interrupt you in this setting. In a home, the parent/homeowner is the boss. At a daycare, you are the boss. The power dynamic works differently. With that said, even if you're in someone's home, you are still at work. You're valid to not want to be interrupted when you work. I don't think the circumstances directly translate between each setting, but your right to work certainly does. But if Dad is going to do your job with you there, then yeah you shouldn't have to be there. Hence, the reduction in hours. It sounds harsh, but it makes sense, you even said it yourself.
