Claimant appeals from a final order of the Labor and Industrial Relations Commission (Commission) denying her claim for compensation on the basis that she was not in the course of employment at the time of her injury. We reverse. The facts are not in dispute. Claimant was employed as a bookkeeper. She was responsible for preparing the payroll, and on Tuesdays, which were paydays, she would deposit a check into employer's payroll account at a local bank. The check was drawn on employer's ""main"" account at a Chicago bank; in order for the check to be posted as of Tuesday, the local bank required that it be deposited before 2:00 p.m. The trip to the bank took approximately one-half hour. Claimant used her own automobile, leaving employer's office at approximately 1:30 p.m.
