15 minutes per 4 hr shift paid and a lunch break paid or unpaid and optional.
law per states may vary and be careful to know them. The feds say any break 15-20 minutes or less is paid and can n ot be deducted when determining overtime.
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 as compensable work hours that would be included in the sum of hours worked during the work week and considered in determining if overtime was worked. 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.
