Business travel refers to any type of geographical transportation that someone undergoes at the behest of his or her employer to perform the duties of a job. One simple way in which an employee may undergo such travel is for training, in which an employer may require that employees go to a central location to receive instruction. Business travel can also include ongoing and regular visitation to various locations in order to provide service or otherwise work with remote teams. This type of travel is always temporary, as the employee eventually returns home, as opposed to “relocation” that is typically permanent
