The Mikron Technology group of Biel has announced that 400 people are to lose their jobs at a plant in Norway because of declining demand in the European mobile telephony business.
The redundancies and closure of the Loerenskog plant near the capital, Oslo, are part of a restructuring plan announced by Mikron two weeks ago.
Mikron is transferring production capacity from the plant to high-demand markets in Asia and South America.
Production machinery from Loerenskog is for the most part to be reused and moved to other Mikron plants.
A statement said the closure decision affected only the Loerenskog plant and orders would be relocated to other Scandinavian plants in Tunsberg (Norway) and Karlskoga (Sweden).
Mikron said the plant closure costs had already been considered in the 2000 accounts.
