I wish you luck with your application
An uncle of mine started off as an office junior at a well known insurance company.
As a child it seemed that my cousins were moving every six months! Looking back it can't have been that often.
He moved wherever he was needed by the company and was rewarded with promotion time and time again. His family were rewarded by an ever increasing standard of living.
He got to the top and is now enjoying himself after taking early retirement. His family were very supportive throughout his career and his children, far from suffering from having to change schools frequently, are now confident adults who are able to make new friends easily.
Whenever I have had to move because of work, I have viewed it as an exciting challenge. Meeting new people, making new friends and living in a different place is so refreshing.
Obviously, as I touched upon earlier, everybodys situation is different and moving may not be suitable for everyone eg those with an autistic child who is traumatised by change, but, for most people I would say go for it!!!
As I understand it, there will help available to deal with the costs of moving house.
I don't think the level of wage is an issue, as, if anything, the cost of living could possibly be cheaper at the new location.
Of course, those lucky enough to be offered employment in Swansea, who have no pressing circumstances that make such a move impossible, are free to turn the job down and remain in Liverpool, but may find it extremely difficult to find alternative employment should they choose this option.
