I can go along with the Nanny Laws up to the point of vacations. Now, I would have to have to weeks Paid vacations A Year! I might want to go home to see my parents, visit an aging Aunt or a childhood friend. I can not do that in just three days. Trust me I am good with kids. They just love me because I would not hurt a child for nothing. I love children to much. My entire family is like that.
One thing I do believe in is not sparing the rod, but you will have to do something really bad. You can't whip kids for every little thing they do. Otherwise, You will waste time for teaching and learning. Regardless to how old the children are, I believe in teaching and learning all day long. You place your shoes here because.... You eat your veggies because... Sometimes You have to be quite and observe things because... You ask questions because... You are never to young to learn in my book.
When you put kids to bed at night you sing a song that says something about going to sleep. When to change a diaper, tell the little one why. They might not understand you now, when they get older they will know because they were told it all their little lives. I teach kids beyond their years by speaking the right words to them. Words of truth are powerful. They also, give the kids wisdom beyond their years.
Now, back to vacation and over-time. It can be a hand shake contract as far as I am concerned. Pay your workers fair wages, whether they know what is fair or not, and give them respect and demand respect in return.
