Employment laws...?

is there a requirement or law that states mandatory breaks?

From the Dept. of Labor website: Federal law does not require lunch or coffee breaks. However, when employers do offer short breaks (usually lasting about 5 to 20 minutes), federal law considers the breaks work-time that must be paid. Unauthorized extensions of authorized work breaks need not be counted as hours worked when the employer has expressly and unambiguously communicated to the employee that the authorized break may only last for a specific length of time, that any extension of the break is contrary to the employer's rules, and any extension of the break will be punished.

Bona fide meal periods (typically lasting at least 30 minutes), serve a different purpose than coffee or snack breaks and, thus, are not work time and are not compensable

Only 19 states have mandated break/lunch periods for adults (and Illinois' only applies to hotel room attendants; Nebraska's only to assembly plants, workshops and mechanical establishment not covered by collective bargaining). Most all states have mandated breaks/lunches for minors.

Since you don't say if you're an adult or a minor, or what state you're in, I can't tell you definitively.

It depends on what state you live in what the legal requirements are. Go to your state department of labor website to find out.

yes, there are federal minimum required breaks for so many hours worked. states can make stronger laws that require more breaks, but not less than the federal. individual employers can offer longer or more breaks but not less than state or federal.
