Opinion for the Court filed by Circuit Judge TATEL.
We have long held that federal employees may not use the Administrative Procedure Act to challenge agency employment actions.
See Fornaro v. James,
I.
Appellants are four air traffic controllers of the Albuquerque, New Mexico Air Traffic Control Center. Two are bargaining unit members represented by the National Air Traffic Controllers Association (NAT-CA) while two are excluded from the unit as supervisors, but agreements between NATCA and the FAA control the pay of all four. Under those agreements, salary levels vary from airport to airport based on the amount and complexity of the air traffic they manage. The controllers believe the Albuquerque Center’s salary level is set too low because, in their view, the site’s traffic figures erroneously exclude certain military flights.

In April 2000, one of the bargaining unit employees, appellant Joseph Filebark II, following the procedure set out in his collective bargaining agreement, filed a grievance about the salary-level classification with the Albuquerque Center. That grievance was denied, and when Filebark asked the union to pursue the matter to arbitration, the union declined. The Center itself later applied to the FAA for a salary-level upgrade, but that request was denied pending validation of the computer systems that measure air traffic. Although NATCA eventually filed a grievance on behalf of employees at the Albuquerque Center, it withdrew that grievance before it was decided. Meanwhile, one of the non-bargaining unit controllers attempted to file a grievance, which was refused. He later sued in the Court of Federal Claims on a contract theory, but the court rejected his claim as outside its Tucker Act jurisdiction.
Todd v. United States,
Having failed to obtain review on the merits through any of these avenues, the controllers brought a two-count complaint in United States District Court for the District of Columbia. Count I sought review of Filebark’s denied grievance, identifying 5 U.S.C. § 7121(a)(1), a provision of the CSRA, as the statutory basis for judicial review of negotiated grievance procedures. Am. Compl. ¶¶ 37-38. Count II sought APA review of the Albuquerque Center’s salary-level classification on behalf of all plaintiffs.
Id.
¶¶ 39-42. Concluding that section 7121(a)(1), rather than authorizing the suit, “precludes [employees with negotiated grievance procedures] from seeking judicial review” of any kind,
Filebark v. U.S. Dep’t of Transp. (Filebark I),
Significantly for our purposes, the FAA is largely exempted from the CSRA by 49 U.S.C. § 40122(g)(1), which directs the FAA to develop “a personnel management system for the Administration that addresses the unique demands on the agency’s workforce,” “notwithstanding the provisions of title 5 [i.e., the CSRA] and other Federal personnel laws.” See also § 40122(g)(2) (“The provisions of title 5 shall not apply to the new personnel management system.... ”). Congress required that “[s]uch a new system shall, at a minimum, provide for greater flexibility in the hiring, training, compensation, and location of personnel.” § 40122(g)(1). In response the FAA created a personnel management system with dispute resolution provisions that largely track those of the CSRA, providing greater review for major adverse actions and no review for minor actions like this pay-scale dispute. The general exemption from the CSRA has certain exceptions, however, as CSRA provisions such as “chapter 71, relating to labor-management relations,” continue to apply. § 40122(g)(2)(C).
Among the provisions in that chapter that still apply is section 7121(a)(1), which requires that collective bargaining agreements contain negotiated procedures for the settlement of grievances, and which the controllers cite as the statutory basis for Count I of their amended complaint.
*1012
This section previously provided that such negotiated grievance procedures would be “the exclusive procedures for resolving grievances which fall within its coverage.” 5 U.S.C. § 7121(a)(1) (1994). In 1994, however, Congress amended section 7121(a)(1) to make negotiated grievance procedures “the exclusive
administrative
procedures for resolving grievances which fall within its coverage.” § 7121(a)(1) (emphasis added). Having held that the earlier version of this section precluded all judicial review for employees with negotiated grievance procedures,
Carter v. Gibbs,
Seeking reversal of the district court’s ruling that they have no cause of action, the controllers make three arguments: (1) that the district court erred in dismissing the bargaining unit members because section 7121(a)(1), as amended, no longer precludes judicial review of negotiated grievance procedures; (2) that by revisiting dismissal of the APA claims, the district court violated the law of the case; and (3) that because their employer is largely exempt from the CSRA, the controllers can maintain an APA cause of action notwithstanding our CSRA preclusion precedents. We consider each argument in turn.
II.
The controllers’ first argument— applicable only to the bargaining unit members — lacks in relevance whatever it might have in merit. It may be true that in amending section 7121(a)(1) Congress intended no longer to preclude all judicial review for employees with negotiated grievance procedures; it may also be true that
Mudge
correctly allowed the employees in that ease to proceed; it may even be true that the district court’s first opinion in this case erroneously used section 7121(a)(1) as justification for dismissing all bargaining-unit employee claims. But even if section 7121(a)(1) no longer has this preclusive effect, it is emphatically untrue that “§ 7121(a)(1)
establishes
[a] federal employee’s right to seek judicial remedy for [a] grievance subject to negotiated procedures in [a] collective bargaining agreement,” as the controllers maintain in their complaint, Am. Compl. ¶ 37 (emphasis added). To the contrary, as the Supreme Court explained in
Whitman v. Department of Transportation,
Because section 7121(a)(1), by itself, provides no right to sue, the bargaining unit employees must point to an independent source of law in order to maintain this action. In
Mudge
a money claim within the Tucker Act jurisdiction of the Court of Federal Claims provided the cause of action,
see
28 U.S.C. § 1491(a)(1);
Mudge v. United States,
Before we address that question, however, we must resolve a preliminary matter. The controllers argue that by reversing its previous denial of dismissal on the APA claims without a change in facts or law the district court violated the law of the case doctrine. In its second opinion, the district court explained the change as based in “the parties’ lack of clarity regarding their arguments,” and held that reconsidering the issue would not violate the law of the case because failing to reconsider would “be erroneous and work a manifest injustice.”
Filebark II,
Reviewing de novo the dismissal of the APA claims,
e.g., Munsell v. Dep’t of Agric.,
We clarified the breadth of these precedents in two recent cases. In
Graham v. Ashcroft,
we held that the lack of any entitlement to judicial review in the CSRA precluded litigation of an employment matter under the APA even where the complaint did not concern “ ‘a
type
of personnel action covered by the CSRA.’”
To be sure, the controllers correctly point out that Congress largely exempted the FAA from the CSRA, and that we have never before had occasion to apply our preclusion cases to employees of an exempt agency. But the upshot of our precedents for this case is absolutely clear. Far from saving an APA claim, Congress’s exemption of these controllers’ agency from the CSRA signals the same thing as Congress’s omission of the type of personnel action at issue in
Graham,
or the type of employees at issue in
Fausto
— namely that Congress intended to provide these employees with no judicial review. This is because we treat the CSRA and Congress’s related employment statutes as covering the field of federal employee claims, and so our cases expressly teach that those left out of this scheme are left out on purpose. Indeed this case is easier than most, for we need make no inferences about the pregnant meaning of legislative silence. In exempting the FAA from the CSRA, Congress made its intent perfectly clear: to “provide for greater flexibility in the hiring, training, compensation, and location of personnel.” 49 U.S.C. § 40122(g)(1). Because giving FAA employees a unique right of access to the courts would frustrate rather than further that intent, proper application of our precedents bars this suit.
See also McAuliffe v. Rice,
The controllers argue that “[wjhatever the scope of the ‘flexibility’ which Congress granted to the FAA, it is inconceivable that Congress authorized the FAA to devise a compensation plan for its Controllers and then violate that plan with impunity and without review.” Appellants’ Opening Br. 30. The controllers never develop this apparent due process argument, nor could they, for even its factual premise is flawed. The controllers do have a remedy: if the FAA fails to live up to its agreements, the union can pursue the matter,
see, e.g.,
Mot. to Dismiss Ex. 9 (union grievance regarding Albuquerque Center salary level), and if the union fails to live up to its duty of representation, the controllers can pursue the union,
see Steadman v. Governor, U.S. Soldiers’ and Airmen’s Home,
III.
Because the controllers identify only the APA as the statutory basis for their claims, and because such claims are precluded by the CSRA as a whole regardless of who brings them, we affirm.
So ordered.
