Frеderick H. Groce filed a complaint against his employer, Eli Lilly & Company (“Eli Lilly”), alleging that Eli Lilly had terminated him in violation of the Americans with Disabilities Act (“ADA”). He also brought state law causes of action against Eli Lilly. The district court granted summary judgment to Eli Lilly on all claims, federal and state. In this appeal, *498 Mr. Groce challenges the district court’s exercise of its supplemental jurisdiction and its grant of summary judgment to Eli Lilly on his Indiana retaliatory discharge claim. For the reasons set forth in the following opinion, we affirm the judgment of the district court.

BACKGROUND
A. Facts
Frederick Groce worked at Eli Lilly on the night shift for more than three years, from July 1992 to November 10, 1995, as a production technician who set calibrations on machines and handled troubleshooting. He was terminated on November 10, 1995, for insubordination, dishonesty and horseplay. The misconduct that led to his termination occurred on November 1, 1995. On that evening, according to Mr. Groce’s immediate .supervisor, Mr. Grocе had ignored his supervisor during the shift; had yelled the word “Clear!” when he knew the machine was not clear; had blown up and popped plastic gloves; had argued with his supervisor about an assignment; and had responded in a disrespectful and insubordinate manner to an explanation his supervisor gave him. Another supervisor reported that Mr. Groce, that same night, had made a whip out of a piece of board and some banding material and was pretending to hit another employee with it.
The next evening, November 2, 1995, two supervisors met with Mr. Groce to discuss the incidents of the previous night. When Mr. Groce denied the misconduct, they told him that they would look into it further. Mr. Groce then went back to work. Around 10:30 p.m., an incident occurred that Mr. Groce characterized as a “near miss.” 1 Mr. Groce was helping his supervisor, Ron Burleson, and a coworker, Tony Hoffman, conduct lock-out procedures on a tray machine. 2 The other twо men were responsible for locking out the equipment; according to Mr. Groce, however, they did not follow proper procedures. Just as Mr. Groce was working on a set screw with his finger, Hoffman “jogged the machine while my hand was in the machine.” R.27, Ex.A at 90. Mr. Groce claimed that Hoffman deliberately tried to injure him and that the incident could have caused Mr. Groce severe injury. Mr. Groce immediately documented the incident, and his supervisor,' Burleson, signed it. Burleson then rеported the incident to his own supervisor.
Around 7 a.m. the next morning, November 3, Mr. Groce reported the near miss incident to Eli Lilly’s safety department. He learned that neither Burleson nor Hoffman had reported it. Later that day, the Area Safety Coordinator scheduled a near miss review meeting to discuss the circumstances .surrounding the possible accident. At the meeting, Mr. Groce implied that the incident may have been a deliberate act by Hoffman and Burleson. Aftеr the Area Safety Coordinator completed his questions, Mr. Groce, his wife and the supervisors at the meeting discussed Mr. Groce’s concerns about his job.
Over the next several days, Mr. Groce’s supervisors interviewed other night shift employees about the November 1 incidents. They then held a lengthy meeting with Mr. Groce on November 7 to discuss his misbehavior, including his propensity to sit down during his shift, 3 and Mr. Groce eventually admitted carrying out the incidents in question. At that point, the personnel manаger in Mr. Groce’s depart *499 ment was convinced that Mr. Groce had demonstrated misconduct, insubordination, and dishonesty; he stated in his Declaration that he completely lost confidence in Mr. Groce’s integrity. After the meeting, Mr. Groce was sent home. When Mr. Groce returned to work on November 10, he was informed that he had been discharged from his employment with Eli Lilly for that misconduct.
B. Decision of the District Court
Mr. Groce brought an action against his employer pursuant to the ADA, alleging that Eli Lilly and its agеnts harassed him because of his disability, namely his hip injury, and failed to accommodate his disability. He also brought state law claims of intentional misrepresentation, negligent misrepresentation, promissory estoppel and retaliatory discharge. The district court granted summary judgment to Eli Lilly.
On the federal ADA claim, the court found that Mr. Groce was not a “qualified person with a disability.” Because his hip injury did not affect his ability to stand or walk, the court determined that he did not suffer frоm a physical impairment and therefore that he had no claim under the statute. The court also specifically found that Mr. Groce failed to present evidence from which a reasonable jury could conclude that Eli Lilly knew of his alleged hip condition. Nor was there evidence that his employer regarded him as impaired. The district court held that Eli Lilly could not be held hable for discriminating against Mr. Groce on the basis of an alleged disability. This summary judgment deсision on the federal ADA claim has not been appealed.
The district court then considered Mr. Groce’s state law retaliatory discharge claim. Mr. Groce alleged that Eli Lilly terminated his employment because he had protested violations of-the Indiana Occupational Safety and Health Act, I.C. § 22-8-1.1-1 to § 22-8-4r-l (“IOSHA”). The court reviewed Indiana’s public policy exception to the employment-at-will doctrine, as enunciated in
Frampton v. Central Indiana Gas Co.,

DISCUSSION
As this case comes to us, Mr. Groce has abandoned all but one of his claims; he appeals only the state retaliatory discharge claim. With respect to that claim, he contends that the district court should have declined supplemental jurisdiction over it and, in the alternative, that he had stated a cognizable claim for wrongful discharge under Indiana law. We review a district court’s supplemental jurisdiction ruling under 28 U.S.C. § 1367(a) de novo.

See Myers v. County of Lake,
A. Supplemental Jurisdiction
Mr. Groce first claims that, after it dismissed the ADA claim, the sole federal claim in the case, the district court was without subject matter jurisdiction over his state law claims. He points out that there was no diversity of citizenship between the parties and that the state law claims do not arise under federal law. Therefore, he contends, the district court should have dismissed his supplemental state law claims without prejudice.
We cannot accept Mr. Groce’s contention. The district court’s original jurisdiction derives from the federal ADA claim that Mr. Groce properly brought to it. The accompanying state claims fall within a district court’s supplеmental jurisdiction if they are “so related to [the federal] claims ... that they form part of the same case or controversy.” 28 U.S.C. § 1367(a). This supplemental jurisdictional statute codifies the principle that “the federal courts’ original jurisdiction over federal questions carries with it jurisdiction over state law claims that ‘derive from a common nucleus of operative fact,’ such that ‘the relationship between [the federal] claim and the state claim permits the conclusion that the entire action before the court comprises but one constitutional “case.” ’ ”
City of Chicago v. International College of Surgeons,
In this case, the district court properly exercised subject matter jurisdiction to decide Mr. Groce’s state law claims under 28 U.S.C. § 1367(a). His state law claims arose out of the same set of facts — those regarding his employment with and termination from Eli Lilly — as his federal claim. Therefore, the district court had subject matter jurisdiction to consider Mr. Groce’s state law claims under § 1367(a). Moreover, our case law makes clear that the district court did not automatically lose that jurisdiction once it granted summary judgment on Mr. Groce’s ADA claim. 6
Nevertheless, as the Supreme Court emphasized in
City of Chicago,
the fact that § 1367(a) authorizes a district court to exercise jurisdiction over state claims “does not mean that the jurisdiction
must
be exercised in all cases.”
City of Chicago,
Mr. Groce further submits', however, that the district court had a duty to examine the propriety of exercising supplemental jurisdiction once the federal claim was dismissed. Because the district court failed to state its reasons for retaining jurisdiction over these claims, he contends, it is impossible , for this court to review the district court’s exercise of its supplemental jurisdiction for an abuse of discretion.
Whether the district court ought to have set forth its reasons for retaining the state claims is an issue that we are not required to reach. That issue is important only if we needed to reach the underlying question of whether the district court should have exercised its discretion to decline jurisdiction over the state law claims. Mr. Groce, however, waived this latter contention by failing to raise it in the district court.
See Sullivan v. Conway,
Although Mr. Groce’s waiver is disposi-tive of the issue in this case, we pause to emphasize that it is the well-established law of this circuit that the usual practice is to dismiss without prejudice state supplemental claims whenever all federal claims have been dismissed prior to trial. Indeed, this presumption counsels that the better practice is for district courts to state explicitly their reasons for taking the opposite course.
See Khan v. State Oil Co.,
Even if there had been no waiver by Mr. Groce, we do not think that the district court’s decision to retain jurisdiction in this case can be described fairly .as an abuse of discretion. The Supreme Court in
City of Chicago
counseled that a district court, in considering the factors set forth in § 1367(c), “‘‘should consider and weigh in each case, and at every stage of the litigation, the values of judicial economy, convenience, fairness, and comity.’ ”
City of Chicago,
B. State Law Claim: Retaliatory Discharge
Mr. Groce alleges that Eli Lilly terminated his employment because he protested violations of IOSHA. 8 The district court dismissed the claim on the ground that he “has not stated a cognizable claim under Indiana law for retaliatory discharge.” R.44 at 15. We review de novo the court’s summary judgment determination and the Indiana case law covering the wrongful discharge of employees-at-will, which was Mr. Groce’s employment status. Mr. Groce contends that the retaliatory discharge claim raises a novel and unsettled question of state law. Eli Lilly responds that Indiana courts often have addressed wrongful discharge claims like Mr. Groce’s and that this case involves a straightforward application of established precedent rather than difficult new issues of state law.
The State of Indiana recognizes two categories of employment — employment for a definite term and employment-at-will.
See Orr v. Westminster Village North, Inc.,
The Supreme Court of Indiana has carved out only two public policy excep
*503
tions to the “venerable at will employment doctrine.”
See Campbell v. Eli Lilly & Co.,
Nevertheless, Mr. Groce insists that he has a statutorily created pеrsonal right to complain about the “near-miss” safety problem, a right found in the IOSHA statute at Indiana Code § 22-8-1.1-38.1. 9 Therefore, he submits, an Indiana state court probably would have entertained this novel, first-impression claim.
We cannot agree with Mr. Groce’s contention. Indeed, we believe that this action by the Indiana legislature makes it even clearer that Mr. Groce has no common law-based cause of action. To be successful in demonstrating that he falls within thе public policy exception to the employment-at-will doctrine, Mr. Groce must show that “a clear statutory expression of a right or duty is contravened” and that his discharge was in retaliation for thé exercise of that right or duty.
See Orr,
Because Mr. Groce did not pursue the remedies provided by the statute on which he wishes to rely, and because the Supreme Court of Indiana is unlikely to expand the at-will exceptions in light of its rеaffirmation of “the vitality of the employment-at-will doctrine in Indiana,”
Orr,
Conclusion
For the foregoing reasons, we affirm the entry of summary judgment by the district court.

Notes
. A "near miss” is ah incident in which employees do not follow appropriate safety procedures and an injury could have occurred.
. "Lock-out” is the procеdure of turning off the power to a machine so that it does not accidentally turn on while someone is trying to repair it.
.Mr. Groce was involved in a car accident in 1982. His hip fracture caused permanent injury, he claims, and he continues to suffer from pain when he stands for prolonged periods of time.
. 28 U.S.C. § 1367(a) states:
[I]n any civil action of which the district courts have original jurisdiction, the district courts shall have supplemental jurisdiction over all other claims that are so related to claims in the action within such original jurisdiction that they form part of the same case or controversy under Article III of the United States Constitution.
. 28 U.S.C. § 1367(c) provides:
The district courts may decline to exercise supplemental jurisdiction over a claim under subsection (a) if—
(1) the claim raises a novel or complex issue of State law,
(2) the claim substantially predominates over the claim or claims over which the district court has original jurisdiction,
(3) the district court has dismissed all claims over which it has original jurisdiction, or
(4) in exceptional circumstances, there are other compelling reasons for declining jurisdiction.

. Section 22-8-1.1-38.1 of the Indiana Code forbids discrimination against an employee who complains about health or safety issues and establishes the method for redress of such discrimination. It states:
Sec. 38.1. (a) No person shall discharge or in any way discriminate against any employee because such employee has filed a complaint or instituted or caused to be instituted any proceeding under or related to this chapter or has testified or is about to testify in any such proceeding or because of the exercise by such employee on behalf of himself or others of any right afforded by this chapter.
(b) Any employee who believes that he has been discharged or otherwise discriminated against by any person in violation of this section may, within thirty (30) calendar days after such violation occurs, file a com-plaipt with the commissioner alleging such discrimination.
Upon receipt of such complaint, the commissioner shall cause such investigation to be made as he deems appropriate. If after such investigation, the commissioner determines that the provisions of this section have been violated, he, through the attorney general, shall, within one hundred twenty (120) days after receipt of said complaint, bring an action in the circuit courts of Indiana. The circuit courts of Indiana shall have jurisdiction to restrain violations of this section and order all appropriate relief, including rehiring, or reinstatement of the employee to his former position with back pay, after taking into account any interim earnings of the employee.
(c) Within ninety (90) days of the receipt of a complaint filed under this section, the commissioner shall notify the complainant in writing of his determination under this section.
