What is the break law when working a day?

I am a former Human Resources manager for a retailer in the Boston area. Had baby and resigned position to become a mom, just so you know I wasn't fired or anything...

If you are an hourly employee, you are entitled to a 30 min unpaid break after 6 hours of work. If you work 8 hours, you are entitled to two 15 minute paid breaks and one 30 min unpaid break. The company I worked for offered a 15 min rest period after 5 hours of work but it is not mandated by law. You are allowed to forgo your 30 min unpaid break if you work through your break and sign your time card that you voluntarily gave up your break. If you work through your 30 min unpaid break without acknowledgement of doing so, your employer can dock you for that 30 min break.

15 minutes for evry 4 hrs of wotk

i know where i live if ur 16 or 17 [yrs old] you have to take a break after 4 hrs. if ur 18+ you get a break 'when you get one' everyplace i have worked at 8 or less hrs of work gets you a 30 minute break. 9+hrs of work gets you an Hr break.

15 minutes for every 4 hours you work
Full-time: 30 minute break (broken into two 15 minute breaks)
Part-time: 20 minute break (broken into two 10 minute breaks)
Temporary: None

BC Canada You have to be given a 1/2 hour break for a meal after working for 5 hours. Employers are not required to provide coffee breaks.

It depends. For a 8 hour day...(2) paid 15 minutes break and (1) lunch of 30 minutes at least...unpaid. However, there are exceptions...i.e., service industry (like waitresses) and also truck drivers.
