Simply because I like learning this stuff...Are you sure your producers are asking you to abide by the correct laws? Child labor laws are different from Child Actor Labor Laws in a BIG way. Most states basically say that as long as your superintendent says you can work that long, then you can. Every thing that I've research on actor labor laws says that in most states you can work a child actor as much as you like. Which is scary when you think that they could be taken advantage of so you have to look to their parent's and school for more guidance. The US Dept of Labor website states:
"In addition, the child labor rules do not apply to:
* Youth employed as actors or performers in motion pictures, theatrical, radio, or television productions;
* Youth engaged in the delivery of newspapers to consumers; and
* Youth working at home in the making of wreaths composed of natural holly, pine, cedar, or other evergreens (including the harvesting of the evergreens)."
http://www.dol.gov/elaws/esa/flsa/cl/exemptions.aspI work with child actors all the time but I have never really thought about it. Even when I've done double or triple casts kids sometimes work 10 of 12s. I hope this helps. You can always contact someone in your state for guidance.
I hope this helps!
