Workers are responsible for bearing all costs that arise as a result of their responsibilities, including those that are related with business travel. When an employee is required to travel outside of their typical geographic area for work-related reasons, it is the person's obligation to reimburse any and all expenses incurred by the trip. The frequency of business travel, the distance travelled, and the employee's position within the organisation all play a role in determining the amount of these, which can range from very little to quite a lot (if it is a director or an employee at a lower level of the organisation).
