After Reporting

1. Document any changes in treatment
2. Keep detailed timeline

Common Questions

What if I'm wrong about the violation?

You're still protected if you had a reasonable, good faith belief that a violation occurred. You don't have to be correct.

How do I prove my employer retaliated?

Timing is often key evidence. If adverse action follows protected activity closely, that's suspicious. Combined with other evidence (changed treatment, inconsistent reasons), you can build a case.

Can I be fired for reporting something internal?

The Illinois Whistleblower Act protects internal reports to supervisors, not just external reports to government agencies.

What if my employer says I had performance problems?

Employers often cite performance to justify adverse actions. If the real reason was retaliation, that's still illegal. Document your performance record before and after protected activity.

Do I have to report externally to be protected?

No. Illinois protects both internal reports (to supervisors) and external reports (to government agencies).
