This is an appeal from a district court order partially denying the petition of the Equal Employment Opportunity Commission (“EEOC”) for enforcement of an administrative subpoena relating to an investigation under the Americans with Disabilities Act (“ADA”), 42 U.S.C. § 12117. The primary issue presented is whether an EEOC administrative subpoena seeking information about job vacancies is enforceable against an employer who asserts that such information is irrelevant because of the employer’s entrenched seniority system.
The district court’s order is a final judgment,
see EEOC v. Citicorp Diners Club, Inc.,
I
The EEOC issued the administrative subpoena in furtherance of its investigation concerning a discrimination claim made by Emily Bexley, a former employee *1273 of Dillon Companies, Inc. (doing business, and referred to herein, as “King Soopers”). Bexley, who began her employment with the company in 1976, is an insulin-dependent diabetic who has worked since 1995 in the Produce Head Clerk position at the King Soopers store in Greeley, Colorado. In January 1996, Bexley informed the Greeley store manager that her doctor had restricted her to a 7:00 a.m. to 3:30 p.m. work schedule. King Soopers determined that it could not accommodate such a work restriction in the Produce Head Clerk position, and asked its store manager to review available positions in the Greeley store to see if there were any that would meet Bexley’s work-schedule restrictions. The store manager identified two such positions — All Purpose Clerk Checker and Courtesy Clerk — but Bexley rejected them because they offered a substantial reduction in, respectively, hours and pay.
Bexley thereupon resigned from the company and filed a charge of disability discrimination with the EEOC, claiming that the jobs she was offered were not a reasonable accommodation of her disability and that she had been constructively discharged. During the course of its investigation of Bexley’s charges, the EEOC issued a subpoena to King Soopers seeking three groups of information: (1) a list of all employees working in the All Purpose Clerk Checker position in the Greeley store in February 1996, identified by name, date of hire, date in that position, and years of seniority; (2) a list of all employees working in that position in the Loveland, Colorado store in February 1996, identified in the same way; and (3) a list of all employees working in that position in the Boulder, Colorado store in February 1996, also identified in the same way. With respect to these requests, the subpoena also sought a “list of specific shift times that All Purpose Clerk-Checkers could be assigned at each of the three above-mentioned stores.” (EEOC App. at 30.) The EEOC claimed it needed this information in order to determine whether or not there was another position available that King Soopers could have offered Bex-ley as a reasonable accommodation.
' After King Soopers refused to comply with the subpoena, the EEOC brought enforcement proceedings before a magistrate judge. In response to the magistrate’s order to show cause, King Soopers argued that the information sought by the EEOC was not relevant to the claims at issue (1) because by offering Bexley the checker position in the Greeley store, King Soopers had complied with its duties under the ADA, and (2) because collective bargaining agreements (“CBAs”) and entrenched company policies at the Boulder and Love-land stores precluded Bexley from taking a position at either of those locations. In rejecting King Soopers’ first argument, the magistrate noted that under Tenth Circuit precedent “it is at least arguable that, if more than one position is available as an accommodation, the employer must offer positions which tend toward equivalency with the employee’s original position.” (App. of EEOC at 12 (citing
Smith v. Midland Brake, Inc.,
*1274 In sum, the magistrate ordered enforcement of the EEOC’s subpoena with respect to its request for information about the Greeley store, but refused to enforce as irrelevant the subpoena’s demand for information concerning the Boulder and Loveland stores. The EEOC’s objections to the magistrate’s order were overruled by the district court. Before us the EEOC appeals the decision below not to enforce the subpoena with respect to its request for information about the Boulder and Loveland stores. 1

“We review the district court’s rulings on subpoenas for an abuse of discretion.” Un
ited States v. Castorena-Jaime,
Congress has empowered the EEOC to investigate charges alleging violations of the ADA, incorporating by reference the enforcement scheme set forth in Title VII of the Civil Rights Act of 1964.
See
42 U.S.C. § 12117. Pursuant to Title VII, once a claim has been filed by an aggrieved individual, the EEOC must conduct an investigation of the allegations. § 2000e-5(b). In connection with its inquiry, the EEOC is entitled to access “any evidence of any person being investigated or proceeded against that relates to unlawful employment practices covered by this title and is relevant to the charge under investigation.” § 2000e-8(a). To obtain such evidence, the EEOC may exercise all of the powers conferred upon the National Labor Relations Board by 29 U.S.C. § 161, including the authority to issue administrative subpoenas and to request judicial enforcement of those subpoenas. § 2000e-9. As noted above, however, “unlike other federal agencies that possess plenary authority to demand to see records relevant to matters within their jurisdiction, the EEOC is entitled to access only to evidence ‘relevant to the charge under investigation.’”
EEOC v. Shell Oil Co.,
The Supreme Court has explained that the “relevancy” limitation on the EEOC’s investigative authority is “not especially constraining.”
Shell Oil,
The information requested by the EEOC in the present case appears on its face to be relevant to Bexley’s charge that she was not offered a reasonable accommodation by King Soopers. If the company had an opening for a position that was a near-equivalent to the one Bexley had surrendered, then King Soopers’ failure to offer her that position would be material to whether the “reasonable accommodation” requirements of the ADA, 42 U.S.C. §§ 12111-12112, had been met. As noted above, however, the magistrate concluded that with respect to the Loveland and Boulder stores such information could
not
be relevant to the EEOC’s investigation because those two stores were subject to CBAs pursuant to which any “vacant” positions were, in reality, already spoken for.
See Midland Brake,
We first note that although in Midland Brake we did discuss the effect that a CBA may have, on the vacancy status of an employment position, we did not have occasion to address the distinct question of whether, a subpoena requesting information about such a position could ever be relevant to an EEOC investigation. In fact, we are dubious of the magistrate’s assumption that the existence of a CBA would necessarily render irrelevant the type of information sought by the EEOC in a case such as this one. 2 Nonetheless, we need not address this particular question for the simple reason that the magistrate’s factual premise was wrong. As the EEOC noted in its objections to the magistrate’s order, the CBAs at the Loveland and Boulder stores do not cover the checker position about which the EEOC sought information. King Soopers, in its response to the EEOC’s objections, accordingly conceded — albeit tucked away in a footnote — • that “the positions at issue here are not covered by a CBA.” (EEOC App. at 70 n. 4.) Although the district court conducted a de novo review of the record, it adopted the magistrate’s order and its reasoning in its entirety. Because the'factual predicate underlying the magistrate’s reasoning— and the district court’s affirmance of the order — was clearly erroneous,' we must *1276 conclude that it was an abuse of discretion for the court to rely on the existence of CBAs at the Loveland and Boulder stores as grounds for quashing the EEOC’s subpoena.
King Soopers argues that we should nonetheless affirm the district court’s partial quashing of the subpoena on the alternative ground that it has a “well-established policy mandating that the employees within a particular store or geographic area have the right to any vacancy within that store or geographic area before anyone from the outside can be considered.” (Appellee’s Br. at 17.) It cites Midland Brake for the proposition that employers are “not required to violate other employment policies in order to provide a reassignment as an accommodation” (id. at 16), and then suggests that, pursuant to this reading of Midland Brake, the information sought by the EEOC in its subpoena cannot possibly be relevant to its investigation. King Soopers’ argument must fail for two reasons.
First, as the EEOC notes in its brief,
Even if King Soopers has a policy of preferring incumbent employees of a given store in filling vacancies, that policy would be relevant to Bexley’s charge only with respect to positions that were filled by incumbents. If King Soopers filled any of the positions with new hires, the asserted policy would have no bearing since Bexley would not have been competing with an incumbent for those positions.
(Appellant’s Br. at 15.) Stated differently, the information requested by the EEOC remains relevant — even in light of King Soopers’ entrenched policy of preferring a store’s incumbent employees when filling vacancies — to determine whether there was in fact a position that was either not offered to any incumbents or not accepted by any incumbent. In such circumstances, a position might in fact have been open to Bexley and offered to her as an accommodation. We agree with the EEOC that the information it seeks through its subpoena might shed light on whether King Soopers in fact followed through on its policy and whether, despite the policy, a position was nonetheless open and available to Bexley as a reasonable accommodation.
Second,
Midland Brake
simply does not state the proposition of law that King Soopers claims. Unlike its more definitive discussion of the consequences that a CBA will have on the “vacancy” status of a potentially open position,
Midland Brake
does not pretend to hold that an employer’s mere assertion of an entrenched employment policy should be determinative of whether a given position is or is not vacant for labor-dispute purposes. In
Midland Brake,
we explained only that “there
may
be other important employment policies besides protecting rights guaranteed under a collective bargaining agreement that would make it unreasonable to require an employer to reassign a disabled employee to a particular job.”
For present purposes, the import of the above-quoted passages is that whether a well-entrenched seniority system suffices to “take off the table” a position that might otherwise serve as a reasonable accommodation is a context-specific inquiry that cannot be resolved in an informational vacuum, based only on the say-so of the employer. This conclusion is buttressed by the Supreme Court’s holding last Term that “[tjhe simple fact that an accommodation would provide a ‘preference’—in the sense that it would permit the worker with a disability to violate a rule that others must obey—cannot,
in and of itself,
automatically show that the accommodation is not ‘reasonable.’ ”
US Airways, Inc. v. Barnett,
Finally, King Soopers briefly argues that the information sought by the EEOC in its subpoena is not relevant because the company already offered Bexley a reasonable accommodation by proffering her a pair of positions at its Greeley store. Rejecting this argument below, the magistrate judge Concluded that the EEOC’s subpoena might have cast light on
whether
King Soopers’ offer of positions with lower pay or fewer hours
was
a reasonable accommodation. As we explained in
Midland Brake,
an employer “may reassign an individual to a lower graded position if there are no accommodations that would enable the employee to remain in the current position and there are no vacant
equivalent
positions for which the individual is qualified with or without reasonable accommodation.”
*1278 III
The district court’s order quashing the EEOC’s subpoena with respect to information sought about King Soopers’ Loveland and Boulder stores is REVERSED. In all other respects the district court’s order is AFFIRMED. This matter is REMANDED with instructions to enforce the EEOC’s administrative subpoena in its entirety.
Notes
. At oral argument, King Soopers confirmed that it does not contest the district court’s decision to enforce the subpoena with respect to the request for information about the Greeley store.
. In its objections to the magistrate's order, for example, the EEOC noted at least one way in which its request for information remains relevant despite the existence of a CBA:
[E]ven under a collective bargaining agreement, when there is a position to be filled, some type of notice goes out or a posting appears in the appropriate place, either of which serves to provide notice of an available position and an opportunity to bid on a position. At some point, an employee either bids on and obtains the ‘vacant’ position, or a new hire occurs to fill the ‘vacant’ position.
(EEOC App. at 56.) It would seem relevant to Bexley's claims to learn whether a position had, in fact, survived the CBA process and resulted in the hiring of a new employee without the position having been offered first to Bexley.
