WORKING ABROAD
According to Eurostat, around 1 million citizens of EU countries are now living
and working in Britain – but there are also around 1 million Britons living and
working in the rest of the EU. Until recently British chose English speaking
countries like the USA or Australia as their destination. Now due to new work
regulations it is much easier to work in any country within the EU. Some of the
most popular destinations are France, Portugal, Spain, Sweden and Denmark. But
is the idea of mobile European workers fact or fiction and what is it like to work in
another country? Finding work abroad can be very challenging. Getting used to a
new way of life, new people and a new culture takes time and effort. Also you will
have new places to visit and maybe a new language to learn. Anyway, moving to a
new country can open up career opportunities that you may not have thought of.
Alexander Thompson, 27, said ‘au revoir’ to the UK and moved to France. He had
studied engineering in Bristol and worked in various companies around England.
But he wasn’t satisfied with work conditions and didn’t see any career prospects.
Also he wanted a different lifestyle. Peter didn’t expect to get a job in his field
immediately. He did a number of different jobs until he was finally hired by
Renault. First he worked there as a technician, then after two years of hard work he
got promoted. After all his experience, he says that his poor level of French was a
big problem at first. He did a two-month language course before he moved to
France, but this still was not enough for his profession. He says that if you want to
get a good job in another country, you have to be able to speak the language really
well. Terry Wilson, 43, is a graphic designer from Scotland. Seven years ago he
went to Switzerland but then he moved to Germany and set up his own advertising
company in Munich*. Now he employs more than 20 people. He says that
Germany is a good place to work in advertising because the Germans think the
British are very creative. He could speak German well before he arrived in the
country. He said that he couldn’t compete with other companies without a good
knowledge of German. Another problem he had there was getting used to new
traffic rules as in Britain you have to drive on your left while in other countries of
Europe you have to do it on the right.
