Does my employer have to give me a break?

• online internet work
• home work business online
• paid search marketing
• strep incubation period

I started a new job and my coworker told me we do not get a paid break, just a 30 min unpaid lunch if we work 6 hours and no breaks at all even if I work 4 and 1/2 hours! :o Isn't this against CA state law??

Additional Details

I don't hate it here ..I just want to know if I get a 10 or 15 minute break/rest period ..I have at every other job ive had in the past
