Don't bother
Hi Pablo,
Sorry to see your post has been hi-jacked by GR600 and turned into a window into his psyche. (Very entertaining).
Don't bother working for GR unless you can't get anything else.
As a company they are going nowhere fast and are deep in debt even after their small profit this year. Job security is an oxymoron in GR. (See 2004/2005 debacle).
Guernsey is a beautiful place but very isolated not just literally. It is VERY expensive to live there, the tax thing helps but they're in the process of introducing a kind of VAT that'll go on everything making things even more expensive.
If you want to build up your hours you'll regret making the effort of moving there etc.
I did work for them and saw the place deteriorate it was time for me to leave and the job market was right too.
If you do end up going to live in Guernsey you will enjoy some things there, it is quite unique, unfortunately GR is not one of those things IMHO.
There are alot of other options out there.
Oh and another thing, Aurigny does not MEAN Alderney in French. It is Alderney's original Norman-French name.
GR 600 you cringemeister...
