OPINION BY Judge BROBSON.

Petitioner Kelvin X. Greer (Claimant) petitions for review of a decision and order of the Unemployment Compensation Board of Review (Board), dated August 24, 2009. The Board reversed the decision of a Referee and declared Claimant ineligible for benefits under Section 402(e.l) of the Unemployment Compensation Law (Law). We affirm the Board's order.

The facts, as found by the Board, are as follows:

1. The claimant was last employed as a Machinist by Lehigh Heavy Forge Corporation [(Employer)] from June of 2001, at a final pay rate of $17.35 per hour. His last day of work was October 31, 2008.

2. The employer's rules state that, "Possession or consumption of alcoholic beverages on plant premises, or reporting to work under the influence of alcohol, and under the influence of drugs, and/or narcotics, or in possession of dangerous drugs and narcotics while on plant premises, or reporting to working under the influence of drugs and/or arranging to buy or sell drugs while on company property, and/or conviction of drug-related crime (Employer's 1) are prohibited."

3. The employer's further explanation of the drug and alcohol policy statement also states that, "Employees suspected of being under the influence of drugs and/or alcohol, be tested for blood levels of drugs and alcohol."

4. The claimant was or should have been aware of this policy as it was publicly posted in the workplace.

5. On October 30, 2008, the employer smelled the odor of alcohol in the claimant's presence.

6. The employer requested that the claimant be tested.

7. The claimant agreed to be tested and was taken to St. Luke's Hospital North.

8. The claimant was given a blood/alcohol test and a drug test.

9. The blood/alcohol test came back negative.

10. The drug test, however, came back positive for cocaine.

11. The claimant admitted to the department on his claimant questionnaire that he failed the drug test when his sample "tested positive for traces of cocaine in my urine."

12. When confronted with the drug test results, the claimant admitted to the employer that he had drug and alcohol problems and that he was planning on enrolling in a treatment program in Altoona Pa.

13. On cross examination the claimant admitted that he ingested cocaine at a party about a week before he was tested and that he knew it was a mistake.

14. The employer was not acting with any discriminatory animus when it demanded that the claimant submit to the testing.

15. The claimant was not subjected to disparate treatment.

(Certified Record (C.R.), Item No. 15 at 1-2.)

Following his discharge, Claimant applied for benefits with the Allentown Un-employment Compensation Service Center, which found Claimant ineligible under Section 402(e.l) of the Law. Claimant appealed. Following a hearing, the Referee awarded benefits, finding that Employer did not meet its burden to prove that Claimant failed the drug test. Employer appealed to the Board. The Board reversed the Referee, holding that Claimant was ineligible for benefits under Section 402(e.l) of the Law. The Board determined that Employer had an established substance abuse policy, Claimant was subjected to drug and alcohol testing in accordance with Employer's policy, and Claimant tested positive for cocaine in violation of Employer's policy.

On appeal, Claimant argues that there is not substantial evidence in the record to support the Board's finding that Claimant tested positive for cocaine in violation of Employer's substance abuse policy. Claimant also argues that Employer's substance abuse policy violated the terms of the CBA.

Pursuant to Section 402(e.l) of the Law, an employer is required to demonstrate (1) that it had an established substance abuse policy and (2) that the claimant violated the policy. UGI Utils., Inc. v. Unemployment Comp. Bd. of Review, 851 A.2d 240, 252 (Pa.Cmwlth. 2004) ( UGI Utilities). If an employer meets its initial burden, a claimant will be rendered ineligible for benefits unless the claimant is able to demonstrate that the employer's substance abuse policy is in violation of the law or a CBA. Id. ("The terms of [the employer's substance abuse] policy may be trumped by statute or collective bargaining agreement, but it is the claimant's burden to develop the record appropriately to succeed in that defense.").

Claimant argues, first, that there is not substantial evidence in the record to support the Board's finding that Claimant tested positive for cocaine in violation of Employer's substance abuse policy, because Employer failed to offer any evidence authenticating the drug test conducted or its purported results. Citing this Court's decision in Ellis v. Unemployment Compensation Board of Review, 749 A.2d 1028 (Pa.Cmwlth. 2000), Claimant contends that the results of the drug test could not be considered by the Board because Employer failed to offer any testimony regarding the chain of custody for the samples taken from Claimant. Claimant further asserts that because Employer failed to demonstrate that the samples were taken from Claimant, Employer was prohibited from introducing the purported results of the testing into evidence. While we agree that chain of custody must be proven before drug test results can be entered into evidence, we do not agree that the Board's finding of fact is not supported by substantial evidence in the record.

Introducing drug test results into evidence is not the sole means by which an employer can demonstrate a claimant violated a substance abuse policy. Violation of an employer's substance abuse policy also can be established by a claimant's own admission that he or she violated the policy. Szostek v. Unemployment Comp. Bd. of Review, 116 Pa.Cmwlth. 7, 541 A.2d 48 (1988). Moreover, a claimant's failure to deny testing positive for drugs when confronted with test results by the employer may constitute an admission by silence. McIntyre v. Unemployment Comp. Bd. of Review, 687 A.2d 416, 418 (Pa.Cmwlth. 1997), allocator den., 548 Pa. 640, 694 A.2d 624 (1997) ("Silence is considered an admission, only when the circumstances are such that one ought to speak and does not.").

Here, the Board's finding that Claimant tested positive for cocaine was based on admissions made by Claimant, not on the results of the drug test itself. First, Claimant admitted on the claimant questionnaire that he "tested positive for traces of cocaine in [his] urine." (C.R., Item No. 2 at 1.) Although Claimant testified that the claimant questionnaire did not accurately reflect the statements he made to the unemployment representative preparing the claimant questionnaire, the Board accepted the claimant questionnaire as written. In an unemployment case, the Board is the ultimate finder of fact, "empowered to make determinations as to witness credibility and conflicting evidence." Architectural Testing, Inc. v. Unemployment Comp. Bd. of Review, 940 A.2d 1277, 1280 n. 2 (Pa.Cmwlth. 2008). Next, when Employer met with Claimant to discuss termination for violation of the substance abuse policy, not only did Claimant fail to deny testing positive for drugs, Claimant admitted to Employer to having both a drug and alcohol problem and that he was seeking treatment. (C.R., Item No. 10 at 41.) Finally, Claimant admitted at the Referee's hearing that he had ingested cocaine about a week before the date of the drug test. ( Id., at 64.) The Board's finding that Claimant tested positive for cocaine is, therefore, supported by substantial evidence in the record.

We address, next, Claimant's contention that Employer's substance abuse policy violated the terms of the CBA. The question of whether a drug test was implemented or requested in violation of a CBA under Section 402(e.l) of the Law is a matter of first impression before this Court. Claimant argues that, in making such a determination, this Court should apply federal labor law.

Claimant asserts that because drug testing has been recognized by the National Labor Relations Board (NLRB) as a mandatory subject of bargaining, Employer is prohibited from instituting drug testing unless it is provided for in the CBA. See Bolden v. Se. Pennsylvania Transp. Autk, 953 F.2d 807, 827 (3d Cir. 1991). Pointing out that it is undisputed that the CBA is silent with regard to drug testing, Claimant argues that because Employer's purported substance abuse policy was established in April 2005 — a year-and-a-half before the CBA was entered into on October 8, 2006 — if such a policy were to remain in effect, Employer would have had to incorporate the policy into the CBA. Notwithstanding the absence of a provision expressly authorizing drug testing, Claimant accepts that a CBA may implicitly permit drug testing based on "practice, usage and custom." Consolidated Rail Corp. v. Railway Labor Executives' Ass'n, 491 U.S. 299, 311, 109 S.Ct. 2477, 105 L.Ed.2d 250 (1989). Claimant contends, however, that because Employer never enforced its substance abuse policy against any employee — save Claimant — the CBA does not implicitly authorize drug testing. For the reasons that follow, we reject Claimant's argument.

Pennsylvania courts have discouraged looking to federal labor law for the purpose of deciding a claimant's eligibility for unemployment compensation benefits. In Penflex, Inc. v. Bryson, 506 Pa. 274, 294, 485 A.2d 359, 369 (1984) ( Penflex), our Supreme Court addressed, inter alia, the question of whether employee participation in a strike, which purportedly violated federal labor law, constituted willful misconduct under Section 402(e) of the Law. Id. at 289-90, 485 A.2d at 367. There, the claimants engaged in a work stoppage before their labor union notified the Federal Mediation and Conciliation Service of the contract dispute as required by Section 8(d) of the NLRA. Id. at 281, 485 A.2d at 362. Consequently, the employer terminated the claimants for participating in what the employer deemed to be an "illegal" strike. Rejecting the employer's argument that participation in a work stoppage in violation of Section 8(d) of the NLRA must be deemed "willful misconduct" under Section 402(e) of the Law, the Supreme Court stated:

To hold that participation in a strike in contravention of federal law constitutes willful misconduct under Section 402(e) would require the courts, in every case, to determine whether an alleged infraction of federal law in fact occurred and, if so, whether the strike must be deemed illegal on account of the infraction. Any such attempt to construe and apply federal law in these situations would constitute an impermissible intrusion into the regulatory jurisdiction of the [NLRB] under Section 8 of the [NLRA].

Id. at 293, 485 A.2d at 369.

Similarly, this Court has held that "the NLRA does not provide a persuasive model for [this] Court's interpretation of the Law." Chavez (Token) v. Unemployment Comp. Bd of Review, 738 A.2d 77, 81 (Pa.Cmwlth. 1999) ( Chavez), allocatur den., 563 Pa. 704, 761 A.2d 551 (2000). In Chavez, the employer made unilateral changes to the employee health plan and the employee handbook during the course of negotiations with the claimants' labor union. Id., at 79. The employer then conditioned continued employment on acceptance of the new health plan and new handbook. As a result, the union commenced a work stoppage. Id. This Court was asked to address the question of whether the strike/lockout analysis under Section 402(d) of the Law applied to a work stoppage initiated by workers represented by a labor union, but who had no existing or recently expired collective bargaining agreement with the employer. Id. at 80. Claimants argued that the strike/lockout analysis should apply due to the fact that the NLRA obligates employers to bargain in good faith over any changes to wages, hours, terms and conditions of employment — otherwise known as mandatory subjects of bargaining — once workers are represented by a certified union. Id. Rejecting the claimants' position, this Court stated:

[Claimants'] reliance on the NLRA is misplaced. The NLRA is designed to regulate collective bargaining, whereas the principal objective of the Law is to alleviate economic distress in individual cases where employees become unemployed through no fault of their own. Accordingly, the NLRA does not provide a persuasive model for the Court's interpretation of the Law. Moreover, if the Court were to adopt petitioner's suggestion that the strike/lockout analysis be applied to the status quo mandated by the NLRA when federal law requires bargaining in good faith, then the Court would needlessly entangle this state's unemployment compensation jurisprudence with the complex body of federal law surrounding the NLRA.

Chavez, 738 A.2d at 81 (citations omitted).

Furthermore, our Supreme Court has discouraged looking beyond the language of a CBA to determine the terms and conditions of employment in the context of unemployment compensation. In Miceli v. Unemployment Compensation Board of Review, 519 Pa. 515, 549 A.2d 113 (1988) ( Miceli), the Supreme Court addressed the question of whether a work stoppage after the expiration of a CBA was the result of a strike or a lockout under Section 402(d) of the Law. Utilizing the Vrotney test, the Supreme Court's analysis was dependent on which party, the labor union or the employer, first altered the "status quo." Id. at 520, 549 A.2d at 115. Consequently, it was necessary for the Supreme Court to determine what constituted the "status quo" between the parties. In our opinion, this Court concluded that "the status quo consisted not only of the terms and conditions of employment under the expired [CBA], but also the previous conduct of the parties." Id. at 525-26, 549 A.2d at 118. The Supreme Court disagreed, finding that this Court erred by considering past practices, and held that a court may not look beyond the terms and conditions of employment, as embodied in the CBA, in determining what constitutes the status quo in an unemployment compensation case. Id. at 525-27, 549 A.2d at 118.

Later, in Behers v. Unemployment Compensation Board of Review, 577 Pa. 55, 842 A.2d 359 (2004) ( Behers), our Supreme Court was again asked to determine if this Court erred by looking beyond the terms and conditions of a CBA in determining what constitutes the status quo in the context of unemployment compensation. Reaffirming its decision in Miceli, the Supreme Court again held that this Court erred by considering past practices, stating:

The Commonwealth Court erred in interpreting Miceli to permit the consideration of "past practices" beyond the express terms of the parties' CBA in determining what constitutes the status quo. Indeed, to consider "past practices" not memorialized in the parties' written agreement would eviscerate the clear and simple rule articulated in Miceli.

Id. at 67-68, 842 A.2d at 367.

Although Penflex, Chavez, Miceli, and Behers do not specifically address Section 402(e.l) of the Law, we find these cases persuasive. The overarching theme in each of these decisions is that, in the context unemployment compensation, standards should be simple and easy to apply at the administrative level. Our Supreme Court has stated:

[T]he Law is designed to allow funds to be obtained by persons unemployed through no fault of their own at the earliest point that is administratively feasible.

To this end, the unemployment compensation system must operate quickly, simply, and efficiently. The proceedings are by design, brief and informal in nature. Thus, the claims for benefits are not intended to be intensely litigated.

Harkness v. Unemployment Comp. Bd. of Review, 591 Pa. 543, 553, 920 A.2d 162, 168 (2007) (citations and quotations omitted). Claimant's standard would require Referees, the Board, and/or the courts to construe and apply the complex system of federal labor law in every instance where it is alleged that an employer's substance abuse policy violates a CBA. Such a standard would be difficult to apply at the administrative level and would invariably be more costly and more time-consuming, as it would necessarily involve delving into past practices and bargaining history. Accordingly, we find application of federal labor law inappropriate. In determining whether Claimant carried his burden of establishing that Employer's substance abuse policy violated the CBA under Section 402(e.l) of the Law, this Court will look only to the language of the CBA itself.

In the present case, Claimant has established, at most, that the CBA is silent with regard to drug testing. This fact alone, however, fails to demonstrate that Employer's substance abuse policy was "trumped" by the CBA. UGI Utilities, 851 A.2d at 252. Although the CBA does not explicitly authorize drug testing, the CBA also does not explicitly prohibit it. Instead, the CBA gives Employer considerable discretion over operation of the facilities and direction of the workforce. Specifically, Section 2 of the CBA, entitled "Management," provides:

The management of the works and the direction of the working forces, including the right to hire, suspend or discharge for proper cause, . . . is vested exclusively in [Employer], unless expressly limited by specific provisions contained in the Agreement.

(C.R., Item No. 6 at 13 (emphasis added).) Notably, no section of the CBA expressly limits Employer's ability to maintain its substance abuse policy, which, as pointed out by Claimant, was authored before the parties entered into the CBA. Moreover, Section 17 of the CBA, entitled "Safety and Health," provides that Employer "shall continue to make reasonable provisions for the safety and health of its employees at the plant during the hours of their employment." (C.R., Item No. 6 at 35.) In light of the above, we hold that Claimant has failed to establish that Employer's substance abuse policy violated the CBA under Section 402(e.l) of the Law.

Accordingly, we affirm the decision of the Board.

ORDER

AND NOW, this 29th day of July, 2010, the order of the Unemployment Compensation Board of Review, dated August 24, 2009, is hereby AFFIRMED.
