Business travel expenses are those that employees pay for while on the job. The cost of this kind of expense depends on how the employee got there (by plane, train, bus, etc.) and what their job is (if it is a director or an employee at a lower level of the organization). Someone looking for work may leave their own city, state, or country. Depending on the length and distance of the business trip, there may be costs for meals, lodging, and other things that are needed to meet business goals.
