Illinois Whistleblower Laws

A whistleblower is someone who notifies authorities about a safety violation or other information about an employer that is a matter of public concern. For example, a coal miner who notifies the Environmental Protection Agency about his employer's illegal dumping of coal ash would be considered a whistleblower.

Because reporting violations to authorities or the appropriate government agency may cost employers money (to pay fines, legal defense counsel, remediation costs, etc.), an employers may retaliate against an employee by taking a number of actions, including:

  • Firing;
  • Disciplining;
  • Blacklisting;
  • Demotion;
  • Suspension; or
  • Denial of pay or benefits.

Since it is in the best interests of the community to address violations -- whether they are environmental, safety-related, legal, financial, etc. -- the federal government and many state governments have enacted laws to encourage reporting by offering whistleblowers some amount of protection against employer retaliation.

It is important to note that in Illinois, whistleblower laws only protect employees of state and local governments. However, as long as they are public employees, employers cannot retaliate if an employee reports:

  • Violation of any law, rule, or regulation;
  • Mismanagement;
  • Gross waste of funds;
  • Abuse of authority; or
  • Substantial and specific danger to public health and safety.

The main provisions of Illinois whistleblower laws are listed in the following table. See Whistleblower Protections for a general overview.
