Importance of Essential Critical Infrastructure
The functioning of special infrastructure is vital for public health, safety, and community well-being. During the COVID-19 pandemic, certain industries are responsible for the continued operation of services, such as healthcare, emergency services, public works, and manufacturing, among others. This infrastructure requires essential workers, such as grocery clerks, doctors and veterinarians, police officers, and firefighters, to name a few.
Essential Employment Categories:
There are 14 essential employment categories listed by the Department of Homeland Security's (DHS) Cybersecurity & Infrastructure Security Agency (CISA). Employees that fall under these categories are referred to as "Essential Critical Infrastructure Workers" and are generally required to deliver services around the clock.
It's important to note that while our list covers the basic essential worker, they may differ in each state. Since each state can individually determine what classifies as essential, employers need to check with their state's government offices before closing down their businesses.
1. Healthcare employees.
The healthcare industry, both public and private, provides essential services that cannot shut down in any circumstance. These essential workers are too valuable in the case of an emergency. For instance, during the COVID-19 pandemic, healthcare employees perform vital services, such as research and testing, patient care, administration of medication to patients, and much more.
Examples of Essential Healthcare Employees:
- Employees conducting critical research about COVID-19.
- Funeral homes, crematoriums, and cemetery workers.
- Employees who support food, shelter, and social services.
