OPINION OF THE COURT
Passavant Retirement & Health Center requests that we review a decision of the National Labor Relations Board which concluded that Passavant committed an unfair labor practice violating section 8(a)(1) and (5) of the National Labor Relations Act (NLRA), 29 U.S.C. § 158(a)(1), (5). Passavant refused to bargain with the General Teamsters, Chauffeurs, Warehousemen and Helpers Local Union No. 538 a/w International Brotherhood of Teamsters, AFL-CIO, the certified exclusive bargaining representative of a group of Licenced Practical Nurses, 1 working as Passavant’s Charge Nurses. The Board cross-petitions us to enforce its decision. Because we find that the LPN Charge Nurses are supervisors under the Act, we will grant Passavant’s Petition For Review, reverse the Board’s ruling, and deny its Petition to Enforce.
I.
Passavant is a continuing care retirement community, providing various levels of nursing services in its skilled nursing facility, separate assisted-living units, and independent-living apartments and cottages. The facility is under the overall supervision of an Executive Director. Directly below the Executive Director in Passavant’s hierarchy is the Director of Clinical Services, who supervises the Independent Living Supervisor and the Director of Nursing. The Director of Nursing has an Assistant Director of Nursing, and both oversee the House Supervisors. Under the House Supervisors are the Head Nurses, who in turn supervise the Charge Nurses. The remainder of the nursing staff includes Nurses Aides and Resident Assistants. In the Independent Living portion of the facility, the Independent Living Supervisor directly oversees the Charge Nurses and Resident Assistants working there. Passa-vant’s Nurses Aides and Resident Assistants are already governed by a collective bargaining agreement.
The Union originally petitioned for representation of all Passavant’s LPNs. LPNs work alongside Registered Nurses as Charge Nurses and Head Nurses. To avoid confusion, it is worth noting that “Head Nurse” and “Charge Nurse” are job titles at Passa-vant, and the terms “Registered Nurse” and “Licenced Practical Nurse” denote different degrees of state licensure. The LPNs and RNs employed in those positions perform the same duties, except that RNs are qualified to perform a few more medical procedures such as drawing blood, and inserting feeding tubes and intravenous tubes. The Union amended its petition to exclude LPN Head Nurses from the proposed bargaining unit, as it recognized that they were supervisors, but did not amend the petition to include RNs employed as Charge Nurses. Thus, the bargaining unit here comprises only LPN Charge Nurses.
While the representation petition was before the NLRB Regional Director, Passavant moved to transfer the proceeding to the Board, which had scheduled oral argument in two cases that also concerned the supervisory status of nurses.
See Nymed, Inc., d/b/a Ten Broeck Commons,
Passavant appealed the Regional Director’s decision to the Board. Meanwhile, after an election, the ballots were impounded pending the Board’s ruling. The Board denied Passavant’s Request for Review, concluding that the Regional Director’s analysis followed the Supreme Court’s recent decision in
NLRB v. Health Care & Retirement Corp.,
*246
The impounded ballots were then counted, and the Union won the election. The Regional Director certified the Union as the exclusive bargaining representative of Passa-vant’s LPN Charge Nurses. The Union requested that Passavant enter into collective bargaining, but Passavant refused. The Union then filed unfair labor practice charges with the Board, and the Board’s General Counsel filed a Complaint against Passavant. The Board granted the General Counsel’s Motion for Summary Judgment, finding that Passavant had violated the NLRA by refusing to bargain.
Passavant Retirement and Health Center,
323 N.L.R.B. No. 99,
The underlying decision of the Regional Director as to the representation election is before us pursuant to section 9(d) of the NLRA, 29 U.S.C. § 159(d). We have jurisdiction over this appeal under 29 U.S.C. § 160(e), (f). Our standard of review is deferential. We will uphold the Board’s findings of fact if supported by substantial evidence in the record as a whole:
“The Board’s findings are entitled to respect; but they must nonetheless be set aside when the record before a Court of Appeals clearly precludes the Board’s decision from being justified by a fair estimate of the worth of the testimony of witnesses or its informed judgment on matters within its special competence or both.”
Universal Camera Corp. v. NLRB,
II.
The Board concluded that by refusing to bargain with the Union, Passavant engaged in an unfair labor practice in violation of section 8(a)(1) and (5) of the National Labor Relations Act:
(a) It shall be an unfair labor practice for an employer—
(1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 157 of this title;
(5) to refuse to bargain collectively with the representatives of his employees, subject to the provisions of section 159(a) of this title.
29 U.S.C. § 158(a)(1), (5) (emphasis added). “The term ‘employee’ shall include any employee ... but shall not include ... any individual employed as a supervisor....” 29 U.S.C. § 152(3). The meaning of the term supervisor, of course, determines this case. In interpreting that term we turn first to the statute itself, which defines a “supervisor” as:
“any individual having authority, in the interest of the employer, to hire, transfer, suspend, lay off, recall, promote, discharge, assign, reward, or discipline other employees, or responsibly to direct them, or to adjust their grievances, or effectively to recommend such action, if in connection with the foregoing the exercise of such authority is not of a merely routine or clerical nature, but requires the use of independent judgment.”
29 U.S.C. § 152(11).
If the LPN Charge Nurses fall within the Act’s definition of supervisors, then it was not an unfair labor practice to refuse to bargain with them. Only two of our past decisions are relevant to this question. Neither, however, directly resolves the issue. In
Tressler Lutheran Home for Children v. NLRB,
*247
Historically, the Board utilized a test for the supervisory status of nurses based on the “interests of the employer” language of section 2(11).

d/b/a Northcrest Nursing Home,
The Supreme Court rejected this analysis in Health Care. First, the Court set forth the proper framework for determining the supervisory status of employees:
“[T]he statute requires the resolution of three questions; and each must be answered in the affirmative if an employee is to be deemed a supervisor. First, does the employee have authority to engage in one of the 12 listed activities? Second, does the exercise of that authority require ‘the use of independent judgment’? Third, does the employee hold the authority ‘in the interest of the employer’?”
Health Care,
“[T]he Board has created a false dichotomy' — in this case, a dichotomy between acts taken in connection with patient care and acts taken in the interest of the employer. That dichotomy makes no sense. Patient care is the business of a nursing home, and it follows that attending to the needs of the nursing home patients, who are the employer’s customers, is in the interest of the employer. We thus see no basis for the Board’s blanket assertion that the supervisory authority exercised in connection with patient care is somehow not in the interest of the employer.”
Health Care
was decided on very narrow grounds. It did not interpret the meaning of “independent judgment” or “responsibly to direct.” Instead, the Court agreed with the Board that those phrases “are ambiguous, so the Board needs to be given ample room to apply them to different categories of employees.”
Id.
The Court also noted that “in applying § 2(11) in other industries, the Board on occasion reaches results reflecting a distinction between authority arising from professional knowledge and authority encompassing frontline management prerogatives.”
Id.
at 583,
Since
Health Care,
the Board has purported to analyze the supervisory status of “charge nurses the same as all other employee classifications and shall apply to them the same test [it] applies to all other employees.”

We need not enumerate every duty performed by Passavant’s LPN Charge Nurses to conclude that they are supervisors. Only one of the twelve statutory indicia need be shown to support a finding of supervisory status.
Health Care,
*248 A. Supervisory Criteria
The Board concluded that Passavant’s Charge Nurses possessed the authority to send Aides home for flagrant conduct violations, such as resident abuse. Earlier, in a nonhealth care case, we determined that this type of authority is clearly disciplinary in nature.
See Warner Co. v. NLRB,
The Board also opined that the “charge nurses can resolve minor problems or ‘gripes’ raised by[nurses aides] and resident assistants concerning daily assignments, break time[s] and the like,” but were not involved in the formal grievance procedure. “[I]t is the higher management authority, rather than LPN charge nurses who are the decision makers with respect to the responses and positions taken by the Employer concerning these [formal] grievances.” Thus, the Board implicitly reasoned that resolving “gripes” does not rise to the level of adjusting grievances under the NLRA. This determination is consistent with other Board decisions.
See Ohio Masonic Home, Inc. v. Teamsters Local Union No. 957,
Passavant argues that the adjustment of even minor grievances is enough to support a finding of supervisory authority, again citing our decision in
Warner. We
agree. In
Warner,
a building supplies business employed drivers and shippers, both supervised by a Yard Manager. The drivers were already unionized, and the employer opposed the shippers’ efforts to establish a union. Testimony revealed that the steward of the drivers’ union often approached the shippers to settle minor complaints. We rejected the Board’s conclusion that this activity did not amount to the adjustment of grievances: “Those so-called ‘minor complaints’ are such disputes as fairly fall under the provision of the drivers’ contract, and which would amount to ‘grievances’ if reduced to writing.”
Warner,
Here, the collective bargaining agreement between Passavant and the Nurses Aides includes sections pertaining to assignments, break times, and lunch breaks. Additionally, its definition of “grievance” is very broad. Just as in Warner, the LPN Charge Nurses at Passavant have the authority to adjust the Aides’ grievances and meet the “supervisory” criterion.
B. Independent Judgment
Because we have concluded that Passavant’s LPN Charge Nurses exhibit two of the statutory criteria, we must now decide whether they exercised that authority with independent judgment. We conclude that they did.
' The Board found that “the authority to suspend employees for flagrant violations such as the abuse of patients is not an indici-um of supervisory authority because no inde *249 pendent judgment is involved because the offenses are obvious violations of the Employer’s policies and speak for themselves.” (App. at 94a n. 53 (citation omitted).) This conclusion is also found in several other Board decisions, including Northerest:
“[Mjany cases indicate that charge nurses have authority to suspend employees for flagrant violations such as drunkenness or abuse of patients. The Board has not found this an indicium of supervisory status because no independent judgment is involved; the offenses are obvious violations of the employers’ policies and speak for themselves---- Accordingly, in making future supervisory determinations, we have decided that whether a ... suspension relates to patient care or not, it will be examined only as to ... in the ease of suspension for flagrant violation, whether independent judgment was involved.”
Similarly, we found in Warner that a supervisor exercises independent judgment when resolving grievances: “What we are concerned about here is the fact that the shippers do resolve disputes over working conditions on behalf of their employer, exercising independent judgment, and thus ‘adjust grievances’ for the purposes of the Act.” Id. at 438. Although we afford deference to the Board, we are not at liberty to ignore our own jurisprudence, which dictates our decision.
Finally, we are not creating a per se rule that LPNs are supervisors. Each case requires a detailed factual application of the twelve statutory criteria. Nor do we take issue with any of the Regional Director’s factual, findings. We do, however, reject its application of the law to the facts.
IV.
In sum, we conclude that the Charge Nurses’ authority to send Aides home for flagrant violations is an exercise of discipline, and when they dispose of minor gripes, they are adjusting grievances; and in both, they are exercising independent judgment. Additionally, the parties do not dispute that this authority is exercised in the interest of the employer. Under these circumstances, we hold that the LPN Charge Nurses are supervisors within the meaning of the Act. Accordingly, we grant Passavant’s Petition for Review, reverse the Board’s order, and deny its Petition to Enforce.
