Pеtitioner Patricia Jan Selk appeals a final decision of the Department of Employment Services’ Office of Appeals and Review (DOES). Mrs. Selk had appealed DOES’s determination thаt she left her employment voluntarily without good cause connected with the work, and was therefore not entitled to benefits. DOES, however, denied her appeal as untimely. She argues, first, that her аppeal was timely because she reasonably relied on information provided by a DOES employee regarding the deadline for her appeal and, second, that the agency’s dеtermination on the merits of her claim is unsupported by substantial evidence in the record as a whole. Upon review of the matter, we agree with petitioner and therefore reverse and remand.
I
Petitioner was employed by the National Savings and Trust Bank, N.A., as a Manual Procedures Analyst. She was subsequently hired as manager for the installation of a new computer system for the bank’s trust deрartment. Problems with the installation of the system arose, requiring Mrs. Selk to work 60 to 80 hours a week. For several weeks she was assigned support personnel; but the bank removed them from the project, еven though the system was not yet functioning smoothly. In Mrs. Selk’s professional judgment, the project continued to require overtime work. Nevertheless, Mrs. Selk’s supervisor told her in July 1983 1 that, although she was expected to work overtime as the project demanded, she would no longer be paid overtime compensation. Mrs. Selk resigned on August 8, 1983.

Mrs. Selk contests DOES’s determination that her appeal was untimely. We agree that under the circumstances it was timely filed.
On August 9, 1983, she filed a claim for unemployment benefits. DOES denied her claim on August 22, 1983. Mrs. Selk telephoned DOES to ask whether the ten days she had in which to note her аppeal referred to calendar days or business days. *1058 The employee to whom she spoke assured her that ten days meant business days. Because the ninth business day was the Friday before Labor Day, the DOES employee told Mrs. Selk that September 6, the Tuesday after the holiday, was her deadline for filing her appeal. She filed in person on that date. DOES subsequently notified her that her appeal was untimely, but that “as a matter of courtesy” she would be heard on the merits. At her “courtesy” hearing, conducted by telephone, 2 she testified to the above jurisdictional facts before thе agency reached the merits of her claim. DOES neither rebutted nor discredited Mrs. Selk’s account of her contact with the agency, which led her to conclude that September 6 was her deadline for appealing its initial determination.
D.C. Code § 46-112(b) (1981) provides that a claims deputy’s determination “shall be final within ten days after the mailing of notice thereof to the party’s last-known address or, in thе absence of such mailing, within ten days of actual delivery of the notice.” 18 DCRR § 4607.1 authorizes the filing of an appeal within the same ten-day period. The days counted are calendar days, not business days. The appeals examiner loses jurisdiction to consider the merits of an appeal filed after the time for filing has expired.
Gosch v. District of Columbia Department of Employment Services,
The facts in this case regarding notice from the agency to the petitioner, however, are identical to those in
Ploufe v. District of Columbia Department of Employment Services,
Ill
Mrs. Selk contends that the agency’s determination on the merits of her claim is unsupported by substantial evidence in the record as a whole. We agree.
Our review of administrative proceedings is limited. We should not disturb a decision if it rationally flows from the facts relied upon and those facts or findings are substantially supported by the evidence of record.
Wаshington Post Co. v. District Unemployment Compensation Board,
*1059 The agency initially determined that Mrs. Selk had voluntarily left her job because of job dissatisfaction, which DOES found was not “good cause connected with the work.” D.C. Code § 46-lll(a) (Supp.1984) & § 46-112(b) (1981). This initial determination may have been justified by the information supplied by Mrs. Selk on her application for benefits. 4 Once the agency decided to entertain her aрpeal as a “courtesy,” however, materials Mrs. Selk submitted and her testimony at her hearing revealed that she had resigned because — among other factors — her assignment continued to require overtime hours, but the bank denied her overtime compensation. At the hearing, her employer’s witness testified that Mrs. Selk and the bank disagreed regarding allocation of resources for the prоject.
In
Kramer v. District of Columbia Department of Employment Services,
Moreover, a final decision by the Office of Appeals and Review should be based not only upon the hearing examiner’s decision, but also on other materials in the record.
See American University v. District of Columbia Department of Labor,
Because no factual determination was ever made regarding the uncompensated overtime claim and because of our serious doubts regarding the fullness of the record before DOES, we cannot say that the final decision in this case was based upon substantial evidence in the record as a whole.
*1060 Accordingly, we reverse and remand for a further hearing and determination in accord with this opinion.
So ordered.
Notes
. Mrs. Selk had been put on the trust project in February 1983.
. From the transcript, Mrs. Selk’s hearing appears to have been by conference cаll. Mrs. Selk, the hearing examiner, the employer’s witness, and Mrs. Selk’s witness — another bank employee — seemed to be able to hear and communicate with one another. In her brief Mrs. Selk points out that the hearing examiner cannot observe the demeanor of witnesses when a hearing is conducted by telephone and is therefore handicapped in making credibility determinations. We сannot be sure on this record whether Mrs. Selk was made aware of her right to be present at the hearing. D.C.Code § 1 — 1509(b) (1981). We do not reach this issue because of our disposition of this appeal оn other grounds.
. DOES counts the date after the "date mailed" or "date delivered" as day number one. Thus a notice mailed on, for instance, March 15 would require filing of an appeal on or befоre March 25.
Gosch, supra,
. She wrote on her aрplication form, filed August 9, 1983, that she quit because she “was given insufficient support for the work [she] was expected to do; disagreed with [her] supervisor over the scope of the project and resources requested to complete the project.”
