Where can I find the federal/state laws regarding 'break time' and 'lunch time' in regard to work conditions?

You might try looking on some federal/state websites rather than FreeLawAnswer.com s.

That would be under Federal Labor Laws. You can look them up online. Just check Labor laws and see what comes up. CHeck with your local law library. They usually are in your court houses or county buildings.

Every state is different so check with the Dept. of Labor and their laws
