The Strand Theatre of Shreveport (“Strand”) petitions for review of a decision and order of the National Labor Relations Board (“Board”) concluding that Strand violated § 8(a)(1), (a)(3), and (a)(5) of the National Labor Relations, Act (“NLRA”), 29 U.S.C. § 158(a)(1), (a)(3), and (a)(5), by unilaterally terminating its use of the Union’s hiring hall, refusing to bargain with the Union, and eliminating the “Regular Employee” position. The Board cross-petitions for enforcement of its order. Because Strand had a 9(a) collective-bargaining agreement with Stage Employees Local 298 (“Union”), Strand waived its argument that the Regular Employee was a statutory supervisor, and the Union did not consent to the elimination of the Regular Employee position, we DENY Strand’s petition for review and GRANT enforcement of the Board’s order.
I. BACKGROUND
Strand, a producer of theatrical plays in Shreveport, Louisiana, since 1925, began using stagehand labor referred by the Union in 1984 after completing a thorough restoration of the theater. Beginning in 1993, Strand and the Union entered into three successive three-year agreements, each of which provided that “STRAND recognizes LOCAL as the exclusive representative of all employees performing work covered by this agreement with respect to wages, hours and working conditions.” The agreement also created the full-time *518 position of Regular Employee, a position held by Stephen Palmer.
In 2002, Strand and the Union agreed to successive one-year extensions of the agreement, the last of which was set to expire on August 15, 2004. Against a backdrop of Strand’s cost cutting efforts, the parties began negotiating a successor agreement on July 22, 2004. That same day Strand placed Palmer, the Regular Employee, on administrative leave. When negotiations proved unacceptable to Strand, it announced that it would not enter into another collective-bargaining agreement with the Union because a nonunion labor supplier, Athalon Group, would significantly reduce labor costs. When the agreement ended, Strand eliminated the Regular Employee position, stopped using Union employees, and began to hire Athal-on to staff its theater jobs.
The Union filed unfair labor charges contesting each of these actions. After a hearing, an Administrative Law Judge (“ALJ”) found that the relationship between Strand and the Union had “matured” into a 9(a) relationship; Stephen Palmer was not a statutory supervisor; the parties did not agree to eliminate the Regular Employee position; and Strand therefore violated the NLRA. The Board adopted and affirmed the ALJ’s decision.

II. STANDARD OF REVIEW
This court will uphold the Board’s decision “if it is reasonable and supported by substantial evidence on the record considered as a whole.” J.
Vallery Elec., Inc. v. NLRB,
III. DISCUSSION
A. Section 9(a) Agreement
Section 9(a) of the NLRA requires employers to bargain with unions that have been “designated or selected for the purposes of collective bargaining by the majority of the employees in a unit appropriate for such purposes.” 29 U.S.C. § 159(a);
see also Nova Plumbing, Inc. v. NLRB,
Sections 8(f) and 9(a) also differ in their treatment of the employer’s bargaining obligation after a contract expires.
See Staunton Fuel,
Notably, an 8(f) union can achieve 9(a) status with proof of majority support.

Strand argues that it did not have a section 9(a) collective-bargaining agreement with the Union because the agreement does not show that the Union represents a majority of employees.

Although the agreement states that the Union is the exclusive bargaining representative of Strand employees, the record lacks evidence of a card check, petition, or election showing the Union’s majority status. Strand’s contention is that 8(f) cases are equally applicable outside the construction industry and that a non-construction union must claim 9(a) status through the same process as an 8(f) con

struction union.

at 718;
see also Am. Automatic Sprinkler,
Strand’s exclusive reliance upon 8(f) construction-industry cases is misplaced because Strand is not engaged in the construction industry, and the Union here is not seeking the “conversion” of an 8(f) agreement into a 9(a) agreement. Moreover,
Staunton Fuel
does not hold, as asserted by Strand, that 8(f) cases apply to non-construction cases or that non-construction unions must follow the same procedure as construction unions to confirm 9(a) status. Strand’s argument flatly contradicts the principle that except in the construction industry, a Union is entitled to a presumption of majority support during and after the contract period, and the agreement need not expressly reflect the Union’s majority status.
See Barrington Plaza,
B. Regular Employee
Strand also seeks review of the Board’s decision that it violated the Act by eliminating the Regular Employee position held by Stephen Palmer on the theory that he was a statutory supervisor unprotected by the NLRA. However, Strand waived this argument by failing to raise it before filing its post-hearing brief to the ALJ.
See Trident Seafoods, Inc. v. NLRB,
Strand finally contends that the Union consented during negotiations to eliminate the Regular-Employee position before the agreement expired. This “concession”, however, followed after Strand unilaterally informed the Union that the position had already been eliminated.
See NLRB v. Katz,
IV. CONCLUSION
Accordingly, Strand’s petition for review is DENIED; the NLRB’s cross-petition for enforcement of its order is GRANTED.
PETITION FOR REVIEW DENIED; ENFORCEMENT GRANTED.
Notes
. The Board has abandoned the "conversion doctrine,” which allowed an 8(f) pre-hire agreement to convert into a 9(a) agreement other than through a Board election or voluntary recognition.
Catalytic,
. The Board urges the court to summarily enforce its finding that Strand violated NLRA § 8(a)(3) and (a)(1) by refusing to hire Union employees because Strand failed to except to this finding. See 29 U.S.C. § 160(e). Strand argues that it cannot be held liable for violations if there was no 9(a) relationship to begin with. Strand acknowledges that if we decide the Union enjoyed 9(a) status, we must uphold the Board’s decision that Strand violated § 8(a)(3) and (a)(1).
. The Board argues that the six-month limitation in NLRA § 10(b) bars Strand from challenging the Union's 9(a) relationship.
