Health Care Security Ordinance. If you have a San Francisco based company with at least 20 employees you are likely very familiar with the Health Care Security Ordinance (HCSO). This law requires employers to pay a fee to the City for all hours worked by all employees. Have you ever wondered if any employees are using this “coverage” that your hard earned dollars are funding? Considering HealthySF is NOT health insurance and there is absolutely no reporting available from the City to promote usage, it can be assumed that your dollars are going significantly/completely unused.
