OPINION DISMISSING WARN ACT CLAIM
SAMUEL L. BUFFORD, Bankruptcy Judge.

I. INTRODUCTION
This case raises the issue of whether the Worker Adjustment and Retraining Notification Act (the "WARN Act" or "the Act"), 29 U.S.C. § 2101-2109 (2006), applies to a trustee in a chapter 7[1] bankruptcy case. While the court does not foreclose a possibility that the WARN Act may apply to an appropriate chapter 7 trustee, the court finds that, under the facts of this case, the chapter 7 trustee was not acting as an "employer" within the meaning of the Act, and thus, was not subject to the Act's requirements. Accordingly, debtor's former employees' WARN Act claim against the trustee is dismissed on the grounds that it fails to state a claim upon which relief can be granted.

II. RELEVANT FACTS
At the time of the filing of the chapter 7 bankruptcy petition, debtor Century City Doctors Hospital ("CCDH") was operating a 176-bed acute care hospital and had approximately 30 patients under care. Immediately upon filing, the trustee obtained authority to operate CCDH for a limited period of time for the purpose of attending to its remaining patients, shutting down its operations and complying *803 with government regulations relating to the disposal of medical waste and hazardous materials. In fact, within the first week after filing, most of the patients were discharged and the remaining patients were transferred to other hospitals.
Plaintiffs are former CCDH employees. Some two hours after the bankruptcy filing, the trustee caused a mass layoff of employees, including some of the plaintiffs. The trustee operated CCDH with the remaining staff members for several days for the limited purpose of providing medical services for the remaining patients and ensuring that CCDH's business was wound up in a timely and efficient manner.
On August 26, 2008, four days after the bankruptcy filing, the trustee mailed out to the remaining plaintiffs a memorandum announcing their termination. Plaintiffs brought this adversary complaint against the estate for violation of the WARN Act.

III. ANALYSIS
The WARN Act requires an "employer" to provide its employees with sixty days notice[2] of a "plant closing" or "mass layoff."[3] 29 U.S.C. § 2102. If the employer fails to do so, it may be liable for up to sixty days' back pay. See id. § 2104. The issue in this case is whether the trustee, acting on behalf of the estate of CCDH, was an "employer" within the meaning of the WARN Act, and was therefore subject to WARN Act notification requirements when plaintiffs were laid off following the chapter 7 bankruptcy filing. If the trustee did not continue operation of CCDH's business as an "employer" under the Act, he was not subject to the Act's notification requirements and the WARN Act claim against him should be dismissed. See In re United Healthcare System, Inc., 200 F.3d 170 (3d Cir.1999).
The WARN Act defines the term "employer" as "any business enterprise that employs 100 or more employees, excluding part time employees...."[4]Id. § 2101. Although the statute does not define the term "business enterprise," the Department of Labor comment provides some guidance as to when a bankruptcy trustee may be a "business enterprise" subject to the WARN Act:
[A] fiduciary whose sole function in the bankruptcy process is to liquidate a failed business for the benefit of creditors does not succeed to the notice obligations of the former employer because the fiduciary is not operating a "business enterprise" in the normal commercial sense.... In other situations, where the fiduciary may continue to operate the business for the benefit of creditors, the fiduciary would succeed to the WARN obligations of the employer precisely *804 because the fiduciary continues the business in operation.
54 Fed.Reg. 16,042, 16,045 (1989). Thus, whether a bankruptcy trustee is an "employer" under the Act turns on the facts of the particular case.
The closest case on point is In re United Healthcare System. Relying on the Department of Labor commentary, the Third Circuit reasoned that the qualification of a debtor in possession in a chapter 11 case as an "employer" under the WARN Act "depends on the nature and extent of the entity's business and commercial activities while in bankruptcy, and not merely on whether employees continue to work `on a daily basis'." Id. at 178. The court further stated;
The more closely the entity's activities resemble those of a business operating as a going concern, the more likely it is that the entity is an `employer;' the more closely the activities resemble those of a business winding up its affairs, the more likely it is the entity is not subject to the WARN Act.
Id. The United Healthcare System court found that the actions of the debtor in possession from the time of filing the case clearly demonstrated an intent to liquidate. Id. In consequence, the court found that the WARN Act did not apply, even though the debtor operated the business under chapter 11 for a period of time.
In contrast to the United Healthcare System case, this is a chapter 7 case. Because there is no caselaw or statutory provision regarding the application of the WARN Act in chapter 7 cases, the Department of Labor's comments are entitled great deference in interpreting a federal labor statute. See, e.g., Chauffeurs, Sales Drivers, Warehousemen & Helpers Union Local 572 v. Weslock Corp., 66 F.3d 241, 244 (9th Cir.1995) (relying on the Department of Labor comments as authoritative interpretations of the WARN Act in determining that a creditor that took possession of a business to enforce a security interest was not subject to the WARN Act); United Healthcare System, 200 F.3d at 176-77 (same).
Under the interpretation of the Department of Labor, a chapter 7 trustee would rarely be subject to the WARN Act, because the trustee does not "operat[e] a `business enterprise' in the normal commercial sense." The purpose of a chapter 7 case is the liquidation of a debtor's business, not its operation. See 11 U.S.C. § 704.
This analysis may not be strictly applicable in all chapter 7 cases. A chapter 7 trustee may decide to operate a business enterprise in the "normal commercial sense" for a period of time, such that the WARN Act may apply to the termination of employees during such operations. Thus, it appears possible that a WARN Act claim could properly be asserted if a chapter 7 trustee were to continue to operate a business for a period of time. The Department of Labor interpretation of the WARN Act supports this view: "[T]he Department does not think it appropriate to exclude all bankrupt companies from the definition of `[employer'.]" 54 Fed.Reg. at 16045. Accordingly, the Department rejected the bright-line rule that a trustee in a bankruptcy case should always be excluded from the definition of employer. Id.
This raises a question of how and how long the trustee must operate the business "in the normal commercial sense" to become subject to the WARN Act. Plaintiffs point to the fact that the trustee did operate the hospital in this case pursuant to court authority for a few days, and argue that this made the trustee subject to the WARN Act.
*805 The court need not decide in this case how long a trustee must operate a business to become subject to the WARN Act. From the outset of this case, the trustee did not operate the business of CCDH "in the normal commercial sense." In accordance with the court's order, the trustee operated CCDH solely for the limited purpose "of shutting down the Debtor's operations and complying with government regulations relating to disposal of medical waste and hazardous materials."
Order Granting Motion for Authority to Operate the Debtor's Business, Aug. 22, 2008. The trustee's intentions have consistently been to close the hospital business at the earliest reasonable time and to liquidate its assets for the benefit of its creditors. The trustee only operated CCDH for approximately a week from the date of filing, and the trustee's brief operation of CCDH was not for any commercial purpose. Thus, the trustee acted solely as a "liquidating fiduciary," rather than an employer "operating a business enterprise in the normal commercial sense."

IV. CONCLUSION
While the court leaves open the question whether the WARN Act can ever apply in a chapter 7 case, it finds the Act is clearly inapplicable in this case. From the outset, this has been a liquidation case. Thus, the chapter 7 trustee is "a fiduciary whose sole function in the bankruptcy process is to liquidate a failed business for the benefit of creditors." The trustee in fact operated the business only for a few days, and solely to complete the care of patients in the hospital, or to transfer them to other facilities. In consequence, the trustee is not an "employer" within the meaning of the WARN Act, and as such, does not succeed to the notice obligations of the former employer. The motion to dismiss the WARN Act claim against the trustee is granted without leave to amend.
