Is there a list of essential industries and employees?

Yes. The Cybersecurity and Infrastructure Security Agency (CISA) has a list of essential industries, available online.

Those industries include:

Healthcare/Public Health (i.e. hospitals and doctors)
Law Enforcement, Public Safety and First Responders (i.e. police and Emergency Management Services)
Food and Agriculture (i.e. farmers and food manufacturers)
Energy (i.e. natural gas and nuclear facilities)
Water and Waste water (i.e. water department)
Transportation and Logistics (i.e. trucking and shipping)
Public Works and Infrastructure (i.e. safety inspectors for public facilities including dams, bridges, etc.)
Communications and Information Technology (i.e. maintainers of communications infrastructure, such as wireless, internet and cable providers)
Community and Local Government (i.e. federal, state, local, tribal and territorial employees who support Mission Essential Functions)
Critical Manufacturing (i.e. metals, PPE, supply chain minerals and employees that support other essential services)
Hazardous Materials (i.e. healthcare waste and nuclear facilities)
Financial Services (i.e. banks)
Chemical (i.e. workers supporting the chemical and industrial gas supply chains)
Defense Industrial (i.e. essential services required to meet national security commitments to the federal government and U.S. Military)
Commercial Facilities (i.e. workers who support the supply chain of building materials)
Residential/Shelter Facilities (i.e. workers in dependent care services)
Hygiene Products and Services (i.e. laundromats, personal and household goods repair and maintenance)

While this guidance is not a federal mandate, and final decisions remain at the state and local levels, we firmly believe it can serve as a baseline for a common national approach in prioritizing essential services and workers.
