The National Labor Relations Board (the “Board”) seeks enforcement of its order finding that Speedway Petroleum, Division of Emro Marketing (the “Company” or “Speedway”) had committed an unfair labor practice as defined in § 8(a)(1) and (5) of the National Labor Relations Act (“NLRA”), 29 U.S.C. § 158(a)(1) and (5), by refusing to bargain with the Board-certified United Food and Commercial Workers International Union, Local No. 35 (the “Union”). The Company opposes enforcement, challenging the certification of the Union as the exclusive bargaining representative of the relevant unit of Company employees. We enforce the order.
I
The Union filed a petition with the Board on June 15, 1983, seeking a representation election in a unit of Company employees. The Regional Director conducted a secret ballot election on July 29, 1983. The tally of ballots revealed that eight ballots were cast, with four cast for representation by the Union, two cast against representation and with two ballots challenged. The Union challenged the ballots claiming that one employee, Kelly Corrigan, was no longer employed by the Company on July 1, 1983, the stipulated cutoff date for voter eligibility, and that another employee, James Smith, was not working for the Company *154 prior to expiration of the eligibility date (App. 43, 48).
The Regional Director conducted an administrative investigation of the challenges pursuant to 29 C.F.R. § 102.69(c)(1) (1984), and on August 19, 1983, issued his Report recommending that the challenges to the Smith and Corrigan ballots be sustained (App. 60-61). The challenge to employee Corrigan’s ballot was sustained because she was determined to be a “casual employee who works on too sporadic a basis to have a community of interest with other employees” (App. 48). The Regional Director sustained the challenge to employee Smith’s ballot because he was hired but not working as of the eligibility date since he had only engaged in certain “pre-work” activities

(App. 50). The Company filed exceptions to the Regional Director’s report, contending that the Regional Director erred in sustaining the challenges and that an evidentiary hearing should have been conducted regarding the challenges. On March 10, 1984, the Board adopted the Regional Director’s findings and recommendations and pursuant to § 9(a) of the NLRA, 29 U.S.C. § 159(a),

certified the Union as the exclusive bargaining representative of the Company’s employees (reported in
Following certification, the Company refused the Union’s request to bargain and to provide the Union with information and was charged by the Regional Director with having committed an unfair labor practice under § 8(a)(1) and (5) of the NLRA. 3 The Company admitted its refusal to bargain and to provide information, but contested the validity of the Board’s certification of the Union. On September 14, 1984, the Board granted its General Counsel’s motion for summary judgment and concluded that all issues raised by the Company in the unfair labor practice proceeding had been or could have been raised in the representation proceeding (272 N.L.R.B. No. 46 (1985)) (App. 135, 137). The Board ordered the Company to bargain with the Union upon request and to provide the Union with previously requested information. The Board seeks enforcement of its order pursuant to § 10(e) of the NLRA, 29 U.S.C. § 160(e).
The Company challenges the Union certification and thereby denies any violation of §§ 8(a)(1) and (5). It opposes enforcement on the grounds that 1) the Board erroneously ignored the parties’ pre-election stipulation and applied Board election policies, 2) both employees Smith and Corrigan were in fact eligible to vote under the relevant Board election policies, 3) neither employee Smith nor Corrigan could be determined ineligible to vote without an evidentiary hearing, and 4) the Board erroneously failed to review all of the evidence relied upon by the Regional Director.

The sole issue in this case is the validity of the Board’s decision to sustain ehal
*155
lenges to Smith’s and Corrigan’s ballots and thereby certify the Union. If the Board’s certification was correct, the Company’s admitted refusal to bargain violated § 8(a)(1) and (5) of the NLRA. We would then be required to enforce the Board’s September 14, 1984, Order. See
NLRB v. Tom Wood Datsun, Inc.,
The Company’s first contention is that the Board ignored the parties’ pre-election stipulation in applying Board election policies to sustain the ballot challenges in this case. The “Stipulation for Certification Upon Consent Election,” entered into and approved by the Regional Director on June 8, 1983, described the voting unit as follows:
All employees employed by the Employer at its Bethalto, Illinois facility, EXCLUDING station manager, office clerical and professional employees, guards and supervisors as defined in the Act (App. 6).
The Company argues that since it is uncontested that both Smith and Corrigan were hired as of the eligibility date, they are both “employees” within the ordinary meaning of that term and must be considered eligible to vote in order to effectuate the parties’ unambiguous intent.
It is well settled that generally pre-election agreements are binding upon the Board. Once it has approved the agreement, the Board’s role with respect to determining the bargaining unit and voter eligibility “is limited to construing the agreement according to contract principles” consistent with the intent of the parties.
Tidewater Oil Co. v. NLRB,
Even if the pre-election stipulation clearly indicates which employees are eligible to vote, it has been held on numerous occasions that the inclusion or exclusion of employees in a unit per a pre-election stipulation may not contravene or violate the NLRA or established or settled Board policy. See
Neuro Affiliates,
Application of the above rules to the present situation indicates that the Board was entirely correct in applying Board policies in its decision to sustain the Corrigan ballot challenge despite the existence of a pre-election stipulation.

The Board sustained the Corrigan ballot challenge because it found that Corrigan was a “casual employee.” Whether we classify the Board policy which excludes from a bargaining unit employees who work on a sporadic and intermittent basis,
i.e.,
“casual employees,” as a settled, established or crystallized Board policy, see
St. Elizabeth Community Hospital v. NLRB,
It is far from clear from a plain reading of the pre-election stipulation’s use of the term “All employees” that the parties evinced a clear intent to include casual employees within the bargaining unit. In similar circumstances courts have rejected the notion that use of general or all-inclusive terms in a pre-election stipulation evidences a clear intent to include all employees not expressly excluded by the broad term. In an opinion written by Judge Friendly, the Second Circuit affirmed the Board’s exclusion of two employees’ ballots where the pre-election stipulation literally provided for the inclusion of “all workers on the payroll during the test period except those expressly excluded.”
Joclin,
Similarly, in Knapp-Sherrill Company v. NLRB, the Fifth Circuit placed the burden of demonstrating intended eligibility under the pre-election stipulation (which would preclude Board application of the community of interest standard) on the party seeking to avoid application of the Board rules and policies:
[ajbsent clear evidence of the parties’ intention to apply some other test, the Board, we think, properly resolved this eligibility question in the same manner as in other cases * * * [i.e.] by determining the extent to which these employees share a community of interests with bargaining unit employees.
In
NLRB v. Boston Beef,
the First Circuit ruled that use of the term “regular part-time employees” in the pre-election stipulation did not evidence an intent to make eligible an employee who worked summers part-time (24 hours per week) under specialized working conditions.
Finally we note that in the cases cited by the Company, where the Board was precluded from applying the community of interest standard, the pre-election stipulation contained relatively specific terminology which identified a particular class of employee rather than the broad and general term “[a]ll employees” involved in this appeal. See
NLRB v. Mike O’Connor Chevrolet-Buick-GMG Co.,
While other evidence of intent regarding the eligibility of a particular employee may come from outside the pre-election stipulation itself, see
Neuro Affiliates,
We next consider whether the Board’s determination that Corrigan was a “casual employee” was supported by substantial evidence. See
Mosey,
The undisputed facts before the Regional Director and the Board, supplied by Corrigan’s and the Company’s own affidavits, revealed that Corrigan was a part-time cashier for one and one-half years for the Company, working twenty to thirty-five hours per week, and that she accepted a new job elsewhere in late June of 1983 (App. 43, 44, 102). The employee agreed with the Company at that time to work under a completely new status where she would lose her guaranteed number of hours (App. 44, 97, 99) and would work on an “on-call” basis on short notice when such work did not interfere with her new job (App. 45-48, 99). She alone worked under this arrangement (App. 47) and in fact did not work during the eligibility period of June 25 to July 1 or at any other time before the election (App. 43-44, 102). She did, however, work parts of three days in August pursuant to the new arrangement (App. 47). Based on these facts, the Board was justified in concluding that Corrigan worked on a “sporadic and intermittent” basis,
Justak Brothers,
The cases cited by the Company do not indicate that the Board applied the wrong legal standard in reaching its eligibility determination and thereby inadequately considered Corrigan’s prior work history and “reasonable expectation” of employment (Br. 21-23). See,
e.g., Montgomery Ward & Co. v. NLRB,
The Company’s contention that an evidentiary hearing was required fares no better. The merits of a ballot challenge may be decided on the basis of an administrative investigation unless the challenge raises substantial and material factual issues. 29 C.F.R. § 102.69(d). See
L. C. Cassidy,
Finally, we refuse to consider Speedway’s argument that the Board erred in the representation proceeding by failing to review all the evidence relied upon by the Regional Director. See
Prairie Tank Southern, Inc. v. NLRB,
The September 24, 1984, Order of the NLRB is enforced.
Notes
. See
NLRB v. Tom Wood Datsun, Inc.,
. Section 9(a) (29 U.S.C. § 159(a)) provides in pertinent part:
Representatives designated or selected for the purposes of collective bargaining by the majority of the employees in a unit appropriate for such purposes, shall be the exclusive representatives of all the employees in such unit for the purposes of collective bargaining in respect to rates of pay, wages, hours of employment, or other conditions of employment
. Section 8(a)(1) and (5) (29 U.S.C. § 158(a)(1) and (5)) provides in pertinent part:
(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.
. The "community of interest” standard is traditionally the touchstone of the Board’s determination whether an individual employee or job classification should be included in a particular collective bargaining unit. The test includes “a consideration of whether the employee works at regularly assigned hours per week; performs duties similar to those of unit employees; and shares the same supervision, working conditions, wages, and fringe benefits as the unit employees.”
NLRB v. Boston Beef Co.,
. Because we affirm the Board's exclusion of employee Corrigan's ballot we do not consider the exclusion of employee Smith’s.
. In
Excelsior Underwear, Inc.,
. Because of our ruling with respect to employee Corrigan, we need not address the Board’s contention that the Company waived any argument regarding the preclusive effect of the preelection stipulation with regard to employee Smith. See § 10(e) of the NLRA, 29 U.S.C. § 160(e);
