If you work at least 2 hours in any 2 week period for an Employer in Chicago, you are covered by the Anti-Retaliation Ordinance. 

The Anti-Retaliation Ordinance prohibits Employers from taking adverse action against Covered Employees for obeying a quarantine order, isolation order, or order from public authorities having to do with COVID-19, and for taking care of someone subject to such an order.
