Saw a tweet from Chris McGinnis on this. Trying to see if the community can contribute some answers.
I think the definition is somewhat open to interpretation. Employees that handle private or sensitive data may need to travel to their offices and that would be seen as essential travel. Alameda County in California is defining essential travel as follows:
For the purposes of this Order, “Essential Travel” includes travel for any of the following purposes. Individuals engaged in any Essential Travel must comply with all Social Distancing Requirements as defined in this Section below.
i. Any travel related to the provision of or access to Essential Activities, Essential Governmental Functions, Essential Businesses, or Minimum Basic Operations.
ii. Travel to care for elderly, minors, dependents, persons with disabilities, or other vulnerable persons.
iii. Travel to or from educational institutions for purposes of receiving materials for distance learning, for receiving meals, and any other related services.
iv. Travel to return to a place of residence from outside the jurisdiction.
v. Travel required by law enforcement or court order.
vi. Travel required for non-residents to return to their place of residence outside the County. Individuals are strongly encouraged to verify that their transportation out of the County remains available and functional prior to commencing such travel.
