There are 16 critical infrastructure sectors whose assets, systems, and networks, whether physical or virtual, are considered so vital to the United States that their incapacitation or destruction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof. Presidential Policy Directive 21 (PPD-21): Critical Infrastructure Security and Resilience advances a national policy to strengthen and maintain secure, functioning, and resilient critical infrastructure. This directive supersedes Homeland Security Presidential Directive 7.
If you work in any of these Critical Infrastructure Sectors and you feel you’ve been retaliated against for raising concerns to your employer or regulators about critical infrastructure, you may contact the U.S. Department of Labor Occupational Safety and Health Administration (OSHA). OSHA’s Whistleblower Protection Program enforces over 20 anti-retaliation statutes that may protect your report. More information can be found at the link below. Complaints with OSHA can be filed online.
