Opinion for the Court filed by Circuit Judge RANDOLPH.
In Junе 1999, Deferiet Paper Company purchased the assets of a paper mill in *582 Deferiet, New York, from Champion International. Champion had collective-bargaining agreements with two unions representing maintenance employees in the mill. Paper, Allied-Industrial, Chemical and Energy Workers, Locals 45 & 56,AFL-CIO (“PACE”) represented production workers and those maintenance department workers classified as welders, masons, oilers, tinsmiths, electricians and instrument mechanics. Local Lodge 1009, District Lodge 65 of the International Association of Machinists and Aerospace Workers, AFL-CIO (“IAM”) represented maintenance employees classified as millwrights, pipefitters, machinists and shift mechanics. Prior to the sale of the mill, there were 102 employees in Champion’s maintenance department. IAM represented 60 of these employees; PACE represented 42. Of the 82 maintenance workers who remained at the mill after the sale to Deferiet, 46 had been represented by IAM and 36 had been represented by PACE. Approximately 300 production employees, who wоrk in the same area of the plant, are represented by PACE.
After Deferiet acquired the mill, each union requested recognition to bargain on behalf of those maintenance employees it had reрresented in the past. Deferiet declined to recognize IAM, claiming that the division between IAM and PACE maintenance employees was no longer appropriate. Instead Deferiet recognized PACE as thе exclusive collective bargaining agent for all production and maintenance personnel.
In the resulting unit clarification proceeding, Deferiet argued that the IAM unit should be accreted to the PACE unit beсause changes in the work duties of plant employees meant that the IAM employees no longer had a separate community of interest. At Champion, maintenance employees were divided by crаft classifications that corresponded to their individual skills (e.g., millwrights, pipefit-ters). According to Deferiet they did little, if any, crossover work between their respective areas of expertise. Deferiet canceled the traditional craft-titled classifications and replaced them with categories for craftspersons called “A,” “B,” “AB” or “AA.” Deferiet also developed a new employee handbook, alеrting employees that they might be required to work in areas other than their traditional craft assignments. Based largely on these changes, and on the allegation that the PACE/IAM distinction was solely the result of an historical аccident, Deferiet sought a determination that the separate units were no longer appropriate.
The Board’s Regional Director determined that Deferiet had made insufficient changes to the operation of the facility to render the existing IAM unit inappropriate. She viewed the reclassification of workers as craftspersons A and B as largely meaningless, since the only basis for assignment to one оf these positions was the historical craft skill of the employees. All of the IAM-represented workers became craftspersons A, and all of the PACE-represented workers became craft-spersons B. Shе found that employees “perform various maintenance duties in essentially the same manner as before the sale,” and concluded that Deferiet “did not make significant changes in the structure and operаtion of the mill.”
The Board denied Deferiet’s request for review. When the company thereafter declined to bargain with IAM, the General Counsel filed a complaint and moved for summary judgment. The Board granted this and issued an order requiring Deferiet to bargain with the IAM upon request. The company petitioned for review and the Board cross-petitioned for enforcement of its order.
Board precedent in successor-employer cases favors the retention of historical bargaining units. “A successor employer is required to recognize and negotiate with the bargaining agent of a predecessor’s employees if the bargаining unit remains appropriate and the successor does not have a good faith doubt of
*583
the union’s continuing majority support.”

Trident Seafoods, Inc. v. NLRB,
Deferiet’s fail-back position is that the old IAM unit is not an appropriate unit despite the presumption in favor of historical bargaining units. Why? Because creation of the IAM unit at the mill was an “historical accident”; because Deferiet substantially restructured the operations of the mill after its acquisition; and because under the Board’s “traditional standards,” a separate IAM unit for some maintenance workers in the newly-acquired mill would be inappropriate. The Regional Director rejected the company’s claims after examining each of its alleged post-acquisition changes, and asking whether the change significantly altered the former IAM unit. But the proper inquiry was not simply whether the evidence showed “significant changes in the operation of the mill since [Deferiet! has assumed control.” Neither the decisions of this court nor those of the Board sanction a purely comparative inquiry.
See Trident Seafoods,
In determining whether a unit is appropriate, the Board exercises wide discretiоn.
Packard Motor Car Co. v. NLRB,
This is not to say that a historical unit will always be upheld in the face of “compelling evidence” of inappropriаteness.
Crown Zellerbach Corp.,
We therefore deny enforcement of the Board’s order, set aside its decision that Deferiet committed unfair labor practices when it refused to recognize the IAM, and remand the case to the Board for further proceedings.
So ordered.
Notes
. Deferiet concedes that it is a successor employer. It does not contest the majority support of IAM within a unit comprised of employees in the crafts this union previоusly represented, but the company denies that majority support exists for IAM within the larger unit of all production and maintenance workers.

Bums
held that a successor employer has an obligation to bargain with the union if the bargaining unit remained unchanged and a majority of the employees hired by the new employer are represented by "a recently certified bargaining agent,”

To this the Supreme Court added: "It would be a wholly diffеrent case if the Board had determined that because [the successor's] operational structure and practices differed from those of [the predecessor employer] and the ... bargaining unit was no longer an appropriate one.”

. We do not believe the court in
Trident Sea-foods
meant to say that in successorshiр cases, the Board approves improper bargaining units. In support of the sentence quoted in the text, the court cited the Board's decision in
Indianapolis Mack.
The Board there ruled that a change in ownership of a facility will not automatically uproot historical units, "as long as they remain appropriate."
