The appellant, Lena Mae Harris, brought this action in the Chancery Court of Copiah County, Mississippi against her employer, Edward Hyman Company (“Edward Hyman”), and her union, Local 361 of the United Garment Workers (“Union”), for restitution and to enforce the provisions of a collective bargaining agreement. Her employer filed a timely 1 removal petition in the United States District Court for the Southern District of Mississippi. 2 As filed, however, the removal petition was defective in that it was not joined in by the Union. 3 Subsequently, Harris moved to remand the action to the Mississippi chancery court. The motion was denied and the action proceeded to judgment against Harris. Harris appeals.
Harris’ appeal focuses solely on whether her action should have been remanded to the Mississippi chancery court. We hold that although the removal petition was defective when filed, by failing to assert promptly her objections to the defects in the petition and by proceeding with discovery, Harris waived her objections to both the procedural irregularities contained in the removal petition and the Union’s untimely consent. Therefore, Harris was pre *945 eluded from seeking a remand to the state court. 4
The ultimate inquiry in this appeal — whether the action should have been remanded to the state court — is not answered simply by noting that the removal petition was defective as filed
5
and that both defendants had not manifested their consent to the petition within the 30-day limitations period set up by the removal statute.

We previously have recognized that strict compliance with the limitations period in the removal statute does not affect the jurisdiction of the district court and that “failure to file the petition within the allotted time may be waived.”
Weeks v. Fidelity & Cas. Co.,
When the motion to remand was heard by the United States magistrate, 7 it was apparent that the Union had consented to Edward Hyman’s petition to remove the action from the Chancery Court of Copiah County. All agreed that the removal petition was defective as originally filed. The only issues were whether Harris had waived her objections to the defects in the removal procedures or whether the Union, by amending its answer, had filed a timely consent to removal.
The order in the record does not indicate upon which ground the magistrate rested his decision.

Reversal is, of course, not justified if the ruling of the district court can be supported on any ground.
Bickford v. International Speedway Corp.,
The record indicates that subsequent to the action being removed from the Chancery Court of Copiah County, Harris served on both Edward Hyman and the Union requests for admissions, requests for production of documents, and a set of interrogatories. Harris also responded to Edward Hyman’s request for the production of documents. Indeed, until the motion to remand was filed, the action proceeded as any other with Harris giving no indication that she was dissatisfied with her federal forum. These acts are consistent with a waiver of a *946 litigant’s right to seek a remand to state court and the district court could have so found.
AFFIRMED.
Notes
. The Judicial Code includes a 30-day limitations period within which a state court defendant is to file its petition for removal in the United States district court.
The petition for removal of a civil action or proceeding shall be filed within thirty days after the receipt by the defendant, through service or otherwise, of a copy of the initial pleading setting forth the claim for relief upon which such action or proceeding is based, or within thirty days after the service of summons upon the defendant if such initial pleading has then been filed in the court and is not required to be served on the defendant, whichever period is shorter.
28 U.S.C. § 1446(b).
Harris’ action was filed in the Chancery Court of Copiah County, Mississippi on July 18, 1979. Eight days later, Edward Hyman filed its petition for removal in the United States District Court for the Southern District of Mississippi.
. An action to enforce the provisions of a collective bargaining agreement may be brought in either state or federal court. R. Gorman, Labor Law 545 (1976). In particular, § 301 of the Labor Management Relations Act, 29 U.S.C. § 185, vests the United States district courts with subject-matter jurisdiction over actions to enforce the provisions of a collective bargaining agreement. See generally R. Gorman, supra, at 545-48. Thus, Harris’ action to enforce the provisions of her collective bargaining agreement properly was removed to the United States district court. See 28 U.S.C. § 1441(a) (“any civil action brought in a State court of which the district courts of the United States have original jurisdiction, may be removed by the defendant or defendants, to the district court of the United States for the district and division embracing the place where such action is pending”).
. All parties agree that the removal petition filed by Edward Hyman in the United States district court was defective when filed. The statute that governs removal from state to federal court has been interpreted, with exceptions inapplicable in the instant case, to “require[] that all defendants join in the removal petition.”
Tri-Cities Newspapers, Inc. v. Tri-Cities Printing Pressmen and Assistants’ Local 349,
. Because we hold that Harris waived her right to object to the defective removal petition and the Union’s untimely consent to removal, we do not decide whether the Union could consent to removal
nunc pro tunc
after the expiration of the 30-day limitation period. Edward Hyman argues that when the Union was granted leave to file an amended answer on October 18, 1979, that the consent of the Union to removal of the action to the district court, which was contained in the amended answer, related back to the filing of the Union’s original answer within the 30-day limitations period.
