Prevention is better than cure. In this case, prevention means explaining the rules of the mobility scheme to employees in advance. We can, of course, provide support in this regard. Once employees start traveling, we always assume good faith; after all, we do not determine whether someone is traveling legitimately or not. And once the trip has been made, it must always be paid for. What we do then is provide insight and overview of trips that “deviate,” e.g., a train trip on the weekend or in the evening. We determine in advance what constitutes a deviation when implementing the mobility scheme. As an employer, you can see from the reports which trips may have been unlawful, and you can discuss this with the employee concerned.
