Can my employer retaliate against me for filing a complaint?

No. Delaware law prohibits retaliation against employees who file a complaint, participate in an investigation, or oppose discriminatory practices.

If your employer takes negative action against you because you asserted your rights, that may be considered a separate violation of the law.

Law Reference: Delaware Code Title 19, Chapter 7 (§711)
