ON PETITION FOR REHEARING
The government has filed a petition for rehearing raising two issues that warrant response.
1. The government’s primary argument is that the panel erred in characterizing the kind of agency interpretation of a statute that is entitled to deference under
Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
That distinction is clearly valid as a general matter: agency interpretations of statutes that are the products of notice and comment rulemaking or formal adjudication are more likely to receive deference than interpretations that have been adopted following less formal means or simply as a matter of agency practice.

deference in eases in which the statute in question is ambiguous, because we consider it clear that 38 U.S.C. § 7421 cannot trump the provisions of title 5 that make RIF procedures applicable to DVA employees in Dr. Von Zemenszky’s position. The government notes that in our initial opinion we stated that “standing on its own, the term ‘conditions of employment’ could be regarded as broad enough to encompass procedures for employee separation.”
In determining whether a statute is ambiguous, a reviewing court “should not confine itself to examining a particular statutory provision in isolation. The meaning — or ambiguity' — of certain words or phrases may only become evident when placed in context.”

2. The government also challenges our construction of the term “conditions of employment” in the VHA collective bargaining statute, 38 U.S.C. § 7422, which we referred to in analyzing the same phrase in section 7421. We pointed out that the same phrase is defined in chapter 71 of title "5, which is specifically .referenced in section 7422. Because “conditions of employment” is defined in 5 U.S.C. § 7103(a)(14) to exclude matters that are “specifically provided for by Federal statute,” that term does not include matters covered by the RIF statutes, which are found in chapter 35 of title 5. The government argues that the RIF statutes specify “very few things for purposes of *1367 § 7103(a)(14),” and that the definition of “conditions of employment” in that provision is therefore not restrictive with respect to RIFs. We disagree. While the details of the RIF rules are set forth in regulations, the general principles are set forth by statute in chapter 35. The government’s position throughout this litigation has been that the RIF statutes are inapplicable to employees in the VHA, not that the RIF statutes are applicable and that the DVA complied with them. If the term “conditions of employment” means the same thing in section 7421 as in chapter 71 of title 5 — and the government does not challenge our conclusion that it does— the consequence is that the term does not encompass those matters that are covered by the title 5 RIF statutes. That result appears to us to be contrary to the government’s legal position in this appeal, i.e., that with respect to VHA employees, the DVA is not constrained by either the RIF statutes or the regulations.
The petition for rehearing is denied.
