a particular employee action is within the scope of employment, Kentucky courts consider the following: (1) whether the conduct was similar to that which the employee was hired to perform; (2) whether the action occurred substantially within the authorized spacial and temporal limits of the employment; (3) whether the action was in furtherance of the employer’s business; and (4) whether the conduct, though unauthorized, was expectable in view of the employee’s duties. Flechsig v. United States, 991 F.2d 300, 303 (6th Cir.1993); Frederick v. Collins, 378 S.W.2d 617, 619 (Ky.Ct.App.1964); Wood v. Southeastern Greyhound Lines, 302 Ky. 110, 194 S.W.2d 81, 83 (1946). We examine each of these factors as they apply to the circumstances of the instant case.
A. Whether Pinion’s conduct was similar to that which she was hired to perform
This Court has recognized that the duties of an employee include those that he or she is “expressly or impliedly” hired to perform. Marcum v. United States, 324 F.2d 787, 790 (6th Cir.1963). Kentucky courts have likewise found that actions “reasonably incident” to an employee’s more typical duties are within the scope of employment. Flechsig, 991 F.2d at 303 (quoting John v. Lococo, 256 Ky. 607, 76 S.W.2d 897, 898 (1934)). Whether the filing of Pinion’s complaint was the type of act she was employed to perform is not therefore a question that can be answered simply by observing that as an accounting technician, it was not part of her normal routine to file criminal charges. Instead, we must examine Pinion’s responsibilities as a postal worker holistically to determine whether they would reasonably include the type of activity at issue.
We begin with the proposition that if Pinion had filed an internal grievance as an actual step in an ongoing disciplinary proceeding, her conduct would have fallen within the scope of employment. This rule, established by the Tenth Circuit in Preble v. Johnson, 275 F.2d 275, 278 (10th Cir.1960), has been accepted by numerous courts considering the issue. See, e.g., Ruderer v. Meyer, 413 F.2d 175, 180 (8th Cir.), cert. denied, 396 U.S. 936, 90 S.Ct. 280, 24 L.Ed.2d 235 (1969); Pagano v. Martin, 397 F.2d 620, 620 (4th Cir.1968), cert. denied, 393 U.S. 1022, 89 S.Ct. 628, 21 L.Ed.2d 565 (1969); West v. Garrett, 392 F.2d 543, 544 (5th Cir.1968); Molever v. Lindsey, 289 F.Supp. 832, 834-35 (E.D.Mich.1968), aff'd, 411 F.2d 597 (6th Cir. 1969). Preble involved a number of libel suits brought by the plaintiff, a former naval employee, in response to which the defendants, other personnel at the base, claimed governmental immunity arising from conduct in the scope of employment or “line of duty.” 275 F.2d at 278. Noting that the Supreme Court has established a flexible test for establishing the line of duty in governmental immunity eases, and that this line must be set at the “outer perimeter” of the employee’s responsibilities, see Barr v. Matteo, 360 U.S. 564, 575, 79 S.Ct. 1335, 1341, 3 L.Ed.2d 1434 (1959), the Preble court wrote: “Surely these federal servants had a clear duty to report to proper authorities causes of disruption in the services they perform, or affecting such services, at the peril of being indifferent if not derelict in their responsibilities.” 275 F.2d at 278. Coleman had become just such a “cause of disruption” with his pattern of abuse and harassment of numerous postal employees, and Pinion would have risked being “indifferent if not derelict” in her responsibilities as a postal employee unless she took action.
The most obvious difference between the Preble line of eases and the situation presented by the instant appeal is that Pinion’s complaint was technically separate from the internal disciplinary proceeding. In that sense, her action was arguably less a part of her job responsibilities. However, we do not believe that this distinction is sufficient to dictate a different result.
The underlying rationale in Preble — that the activities were within the scope of employment because they contributed to the effective management of the employer’s operation — is equally applicable here. Pinion’s criminal complaint was a logical continuation of the recently concluded postal disciplinary proceedings. Postal authorities requested that Coleman file the complaint. Although this was a request and not an order from her
