29 C.F.R. §§ 790.6–790.8

Section 4 of the Portal Act does not affect the computation of hours worked within the “workday” proper, roughly described as the period “from whistle to whistle,” and its provisions have nothing to do with the compensability under the Fair Labor Standards Act of any activities engaged in by an employee during that period. 34 Under the provisions of section 4, one of the conditions that must be present before “preliminary” or “postliminary” activities are excluded from hours worked is that they ‘occur either prior to the time on any particular workday at which the employee commences, or subsequent to the time on any particular workday at which he ceases’ the principal activity or activities which he is employed to perform. Accordingly, to the extent that activities engaged in by an employee occur after the employee commences to perform the first principal activity on a particular workday and before he ceases the performance of the last principal activity on a particular workday, the provisions of that section have no application. Periods of time between the commencement of the employee's first principal activity and the completion of his last principal activity on any workday must be included in the computation of hours worked to the same extent as would be required if the Portal Act had not been enacted. 35 The principles for determining hours worked within the “workday” proper will continue to be those established under the Fair Labor Standards Act without reference to the Portal Act, 36 which is concerned with this question only as it relates to time spent outside the “workday” in activities of the kind described in section 4. 37

“Workday” as used in the Portal Act means, in general, the period between the commencement and completion on the same workday of an employee's principal activity or activities. It includes all time within that period whether or not the employee engages in work throughout all of that period. For example, a rest period or a lunch period is part of the “workday”, and section 4 of the Portal Act therefore plays no part in determining whether such a period, under the particular circumstances presented, is or is not compensable, or whether it should be included in the computation of hours worked. 38 If an employee is required to report at the actual place of performance of his principal activity at a certain specific time, his “workday” commences at the time he reports there for work in accordance with the employer's requirement, even though through a cause beyond the employee's control, he is not able to commence performance of his productive activities until a later time. In such a situation the time spent waiting for work would be part of the workday, 39 and section 4 of the Portal Act would not affect its inclusion in hours worked for purposes of the Fair Labor Standards Act.

Since section 4 of the Portal Act applies only to situations where employees engage in “preliminary” or “postliminary” activities outside the workday proper, it is necessary to consider what activities fall within this description. The fact that an employee devotes some of his time to an activity of this type is, however, not a sufficient reason for disregarding the time devoted to such activity in computing hours worked. If such time would otherwise be counted as time worked under the Fair Labor Standards Act, section 4 may not change the situation. Whether such time must be counted or may be disregarded, and whether the relief from liability or punishment afforded by section 4 of the Portal Act is available to the employer in such a situation will depend on the compensability of the activity under contract, custom, or practice within the meaning of that section. 40 On the other hand, the criteria described in the Portal Act have no bearing on the compensability or the status as worktime under the Fair Labor Standards Act of activities that are not “preliminary” or “postliminary” activities outside the workday. 41 And even where there is a contract, custom, or practice to pay for time spent in such a “preliminary” or “postliminary” activity, section 4(d) of the Portal Act does not make such time hours worked under the Fair Labor Standards Act, if it would not be so counted under the latter Act alone. 42

The words “preliminary activity” mean an activity engaged in by an employee before the commencement of his “principal” activity or activities, and the words “postliminary activity” means an activity engaged in by an employee after the completion of his “principal” activity or activities. No categorical list of “preliminary” and “postliminary” activities except those named in the Act can be made, since activities which under one set of circumstances may be “preliminary” or “postliminary” activities, may under other conditions be “principal” activities. The following “preliminary” or “postliminary” activities are expressly mentioned in the Act: “Walking, riding, or traveling to or from the actual place of performance of the principal activity or activities which (the) employee is employed to perform.” 43

The statutory language and the legislative history indicate that the “walking, riding or traveling” to which section 4(a) refers is that which occurs, whether on or off the employer's premises, in the course of an employee's ordinary daily trips between his home or lodging and the actual place where he does what he is employed to do. It does not, however, include travel from the place of performance of one principal activity to the place of performance of another, nor does it include travel during the employee's regular working hours. 44 For example, travel by a repairman from one place where he performs repair work to another such place, or travel by a messenger delivering messages, is not the kind of “walking, riding or traveling” described in section 4(a). Also, where an employee travels outside his regular working hours at the direction and on the business of his employer, the travel would not ordinarily be “walking, riding, or traveling” of the type referred to in section 4(a). One example would be a traveling employee whose duties require him to travel from town to town outside his regular working hours; another would be an employee who has gone home after completing his day's work but is subsequently called out at night to travel a substantial distance and perform an emergency job for one of his employer's customers. 45 In situations such as these, where an employee's travel is not of the kind to which section 4(a) of the Portal Act refers, the question whether the travel time is to be counted as worktime under the Fair Labor Standards Act will continue to be determined by principles established under this Act, without reference to the Portal Act. 46

An employee who walks, rides or otherwide travels while performing active duties is not engaged in the activities described in section 4(a). An illustration of such travel would be the carrying by a logger of a portable power saw or other heavy equipment (as distinguished from ordinary hand tools) on his trip into the woods to the cutting area. In such a situation, the walking, riding, or traveling is not segreable from the simultaneous performance of his assigned work (the carrying of the equipment, etc.) and it does not constitute travel “to and from the actual place of performance” of the principal activities he is employed to perform. 47

The report of the Senate Committee on the Judiciary (p. 47) describes the travel affected by the statute as “Walking, riding, or traveling to and from the actual place of performance of the principal activity or activities within the employer's plant, mine, building, or other place of employment, irrespective of whether such walking, riding, or traveling occur on or off the premises of the employer or before or after the employee has checked in or out.” The phrase, actual place of performance,” as used in section 4(a), thus emphasizes that the ordinary travel at the beginning and end of the workday to which this section relates includes the employee's travel on the employer's premises until he reaches his workbench or other place where he commences the performance of the principal activity or activities, and the return travel from that place at the end of the workday. However where an employee performs his principal activity at various places (common examples would be a telephone lineman, a “trouble-shooter” in a manufacturing plant, a meter reader, or an exterminator) the travel between those places is not travel of the nature described in this section, and the Portal Act has not significance in determining whether the travel time should be counted as time worked.

Examples of walking, riding, or traveling which may be performed outside the workday and would normally be considered “preliminary” or “postliminary” activities are (1) walking or riding by an employee between the plant gate and the employee's lathe, workbench or other actual place of performance of his principal activity or activities; (2) riding on buses between a town and an outlying mine or factory where the employee is employed; and (3) riding on buses or trains from a logging camp to a particular site at which the logging operations are actually being conducted. 48

Other types of activities which may be performed outside the workday and, when performed under the conditions normally present, would be considered “preliminary” or “postliminary” activities, include checking in and out and waiting in line to do so, changing clothes, washing up or showering, and waiting in line to receive pay checks. 49

As indicated above, an activity which is a “preliminary” or “postliminary” activity under one set of circumstances may be a principal activity under other conditions. 50 This may be illustrated by the following example: Waiting before the time established for the commencement of work would be regarded as a preliminary activity when the employee voluntarily arrives at his place of employment earlier than he is either required or expected to arrive. Where, however, an employee is required by his employer to report at a particular hour at his workbench or other place where he performs his principal activity, if the employee is there at that hour ready and willing to work but for some reason beyond his control there is no work for him to perform until some time has elapsed, waiting for work would be an integral part of the employee's principal activities. 51 The difference in the two situations is that in the second the employee was engaged to wait while in the first the employee waited to be engaged. 52

An employer's liabilities and obligations under the Fair Labor Standards Act with respect to the “principal” activities his employees are employed to perform are not changed in any way by section 4 of the Portal Act, and time devoted to such activities must be taken into account in computing hours worked to the same extent as it would if the Portal Act had not been enacted. 53 But before it can be determined whether an activity is “preliminary or postliminary to (the) principal activity or activities” which the employee is employed to perform, it is generally necessary to determine what are such “principal” activities. 54

The term “principal activities” includes all activities which are an integral part of a principal activity. 61 Two examples of what is meant by an integral part of a principal activity are found in the Report of the Judiciary Committee of the Senate on the Portal-to-Portal Bill. 62 They are the following:

Among the activities included as an integral part of a principal activity are those closely related activities which are indispensable to its performance. 64 If an employee in a chemical plant, for example, cannot perform his principal activities without putting on certain clothes, 65 changing clothes on the employer's premises at the beginning and end of the workday would be an integral part of the employee's principal activity. 66 On the other hand, if changing clothes is merely a convenience to the employee and not directly related to his principal activities, it would be considered as a “preliminary” or “postliminary” activity rather than a principal part of the activity. 67 However, activities such as checking in and out and waiting in line to do so would not ordinarily be regarded as integral parts of the principal activity or activities. 67
