The Isle of Man has very low unemployment, largely because of the financial sector. Seasonal work in the tourism industry is available, but note that a Work Permit is required to work on the island including persons from the UK obtainable from the Isle of Man Government. (http://www.gov.im)
There is no university on the island, although the University of Liverpool runs some courses. There is an Isle of Man College, and an International Business School (http://www.ibs.ac.im).
Hike
There are many hiking/walking trails and footpaths on the isle of man, the most significant being the raad ny foillan the way of the gull which is a 95-mile footpath around the island. other trails cross the island in various locations. the raad ny foillan follows the coast for much of its route and is really quite a spectacular hike, well worth the time and effort while visiting the island.
