San José’s Opportunity to Work Ordinance went into effect on March 13, 2017. The total number of covered workers is calculated by first multiplying the total city employment by the private-sector share of total employment in the San José-Sunnyvale-Santa Clara, CA metropolitan statistical area (MSA), and then multiplying that result by the national share of workers who are hourly. Calculations are made using unrounded numbers. Since the law applies to businesses with 36 or more employees and the data only allow us to consider firms with 50 or more employees, we are likely underestimating the number of covered workers. Further, since the law applies to establishments with 36 or more employees worldwide and we are using firms with 50 or more employees in San José-Sunnyvale-Santa Clara, CA MSA, we are likely further underestimating the number of workers impacted.
