Business trip

A business trip or official trip is a travel/journey caused by business necessities. The place of employment is left temporarily, e.g.

* to visit customers, suppliers or a trade fair
* to participate in congresses or seminars
* for further education
* for excursions for research, scientific campaigns
* for teachers to participate in study trips, school or exploratory trips
* for work in civil engineering, construction, geology, etc.

Business trips have to be approved by the employer, who usually meets the costs. The traveling expenses can be calculated in detail or by a lump sum, depending on the average expense of the travel country.

For activities away, the correspondent term in military is duty travel, in politics facility trip.
