Final answer:
San Francisco is the city that requires all restaurants to provide paid sick days to all employees, reflecting its commitment to progressive labor laws.
Step-by-step explanation:
The city that requires all restaurants to provide paid sick days to all employees is San Francisco. San Francisco has been known for its progressive labor laws, including higher minimum wages and protections for workers. The policy on paid sick days is part of a broader set of labor laws aimed at ensuring that workers, particularly those in low-wage jobs, have access to basic benefits that support their health and well-being. Similarly, cities like Seattle and New York City have also passed ordinances requiring paid sick leave, along with a higher minimum wage to address the cost of living in these areas and ensure that workers can afford essentials like food, clothing, shelter, and healthcare.
