California defines medium exposure risk as being applicable to anyone with high-frequency contact with the general population, meaning that approximately half of its workforce falls into that category. More details are shared below.
Federal: Medium Exposure Workers
- Definition: The federal government (via Occupational Safety and Health Act or OSHA) defines medium exposure as: “jobs include those that require frequent and/or close contact with (i.e., within 6 feet of) other people who may be infected with SARS-CoV-2.”
State of California: Medium Exposure Workers
- Definition: California defines medium exposure as “employees with high-frequency contact with the general population”.
- Types of workers: Teachers and teaching assistants, high-population work environments, and some high-volume retailers qualify for this category.
- Numbers of workers: In California, there are 319,004 teachers.
- Number of workers: The number of retail workers in California is 3.7 million.
- Number of workers: The number of employees in “high-population work environments” is more difficult to determine as it depends on the layout of offices, factories, and other large workspaces. However, the percentage of employees in California that work at small businesses (with less than 500 employees) is 48.8 percent or 7 million. Therefore, the number of employees who work at larger employees is 51.2 percent of the population, or ~7.34 million (7 / 0.488 = 14.3443; 14.3443 x 51.2% = 7.3442816, or ~7.34). This figure most likely includes most of the 3.7 million retail workers (meaning the upper cap is closer to ~7.34).
