Congrats on starting a food business in San Diego! Without more information, It would be irresponsible of me to give a quick answer so I’ll refer you to some sources instead. In a nutshell, if you and your employees are paid salary and have exempt status, then you might not have to pay overtime. But no one is exempt from the labor rules. I would have to know their job titles/roles, responsibilities to determine whether they qualify for the exempt status. Here are some helpful resources:

To help you focus on your food business and get out of the employment law business, consider using a payroll provider that provides HR consulting services as well. https://fitsmallbusiness.com/finding-the-right-payroll-solution/
Best of luck to you!
