OPINION
Carrie Tritchler was employed as a court reporter by the Lake County Superi- or Court (“Superior Court”) from 1989 until May 22, 1996, when her employment was terminated for reasons that are not directly related to this litigation. She had been supervised by defendant Lee Poole from the commencement of her employment until he was terminated in 1994 as a consequence of Tritchler’s sexual harassment complaint. After two jury trials resulting in two verdicts against her, the first of which this court reversed due to inconsistent jury findings, Tritchler now *1153 appeals the most recent verdict on grounds of lack of jurisdiction, errors of law and errors at trial.
Under 28 U.S.C. § 1331, the district court had original jurisdiction of the Title VII claims in Tritchler’s original complaint and supplementary jurisdiction over her California Fair Employment and Housing Act (FEHA) claims under 28 U.S.C. § 1367. Tritchler dropped her Title VII claims on the eve pf the first trial in late 1997, leaving only state claims. On several occasions after that, all parties assented to the district court’s retaining supplemental jurisdiction, but in July 2001, Tritchler changed her position at a hearing on the defendants’ motion for summary judgment. Although she now contests the district court’s continued exercise of jurisdiction, this court has jurisdiction to hear her appeal under 28 U.S.C. § 1291.
Jurisdictional Arguments
A district court’s decision whether to retain jurisdiction over supplemental claims once the original federal claims have been dismissed is reviewed for abuse of discretion.
Brown v. Lucky Stores, Inc.,
With respect to Poole, it is not necessary to determine whether Poole was an employee of the Superior Court (and therefore the State) or an employee of Lake County — or, for that matter, which entity would have been ultimately responsible for any judgment against him — because Tritchler has overlooked one key and decisive fact: Poole explicitly waived the immunity defense, by failing to assert it in his Answer and by later affirmative declaration.
Cf. Hill v. Blind Indus. and Servs. of Md.,
Because defendant Superior Court did plead Eleventh Amendment immunity, we must reach Tritchler’s substantive argument, brazen though it is given her own repeated assent to the district court’s continued exercise of jurisdiction. It is unnecessary to decide whether the district court erred in determining that the Superior .Court had waived the immunity that it pleaded, because Tritchler does not have standing to raise the immunity defense on behalf of the Superior Court in the first place, and tbe Superior Court has very clearly announced that it does not want to assert the defense, given that it has won (twice) on the merits. Following Tritch-ler’s argument to its logical conclusion, a losing plaintiff could raise an immunity claim belonging to the State so long as the State had pleaded it, and would thereby get another bite at the apple. Moreover, as -soon as the State pleaded its immunity defense, the district court would apparently lose jurisdiction, a result not contemplated either by the Eleventh Amendment or by the case law. We have stated that Eleventh Amendment immunity “does not
*1154
implicate a federal court’s subject matter jurisdiction in any ordinary sense” and that it “should be treated as an affirmative defense.”

Claimed Errors of Law
We review the district court’s conclusions of law de novo.
Zivkovic v. So. Cal. Edison Co.,
Tritchler argues that the California Supreme Court’s decision in
Johnson v. City of Loma Linda,
. Claimed Errors at Trial
A district court’s formulation of jury instructions is reviewed for abuse of discretion, and harmless errors do not require reversal.
Monroe v. City of Phoenix,
*1155
There is a California Appeals Court decision, not cited by any of the parties, which states that the duty to investigate is an affirmative obligation. In the context of an employee who sued for psychological and emotional distress due to an investigation of racial discrimination claims against him, the court found that “[p]rompt investigation of a discrimination claim is a necessary step by which an employer meets its obligation to ensure a discrimination-free work environment.”
Northrop Grumman Corp. v. Workers’ Comp. Appeals Bd.,
Tritchler next argues that the district court improperly required the jury to focus on the conduct of named individuals rather than on the overall working conditions she encountered at her place of employment. While it is true that the Special Verdict form did mention specific individuals and did not mention that the “totality of the circumstances” should be considered, the jury instructions for this issue had included specific names in accordance with Tritchler’s wishes. Since the jury was further instructed to consider all of the circumstances, and the Special Verdict form for this question referenced the jury instructions, which stated that “[i]n determining whether an environment is hostile or abusive, you must consider all of the circumstances,” the Special Verdict form was not in error.
A district court’s evidentiary rulings are also reviewed for abuse of discretion, and the appellant is additionally required to establish that the error was prejudicial.
Freeman v. Allstate Life Ins. Co.,
Last, Tritchler argues that she was barred from making offers of proof with regard to various motions in limine. However, she fails to specify in her opening brief what offers were barred and how she was prejudiced. Tritchler has therefore failed to demonstrate that any particular district court ruling was erroneous, or that she was prejudiced in any way by these rulings. Thus, there was no error.
Conclusion
Tritchler’s remaining issues are not claimed to require reversal; rather, they are claimed to apply if we were to remand for a new trial. However, because Tritch-ler has not shown that any of the district court’s findings are erroneous, these issues *1156 are irrelevant, since the decision of the district court is
AFFIRMED.
