Swings and roundabouts. The intention to invest in high speed rail as a replacement for a third runway will generate jobs. One door closes another opens, etc.
If the company were so reliant on a single project they'd have probably left anyway to be honest. That said if they're a small company it seems a bit weird they'd make 200 people redundant in the UK and move operations to Europe. Doesn't fit my definition of 'small'
I have no idea what your skills are - if they're in IT the job market in the fields I get contacted over, largely networking, has picked up significantly.
The economy sucks, the case for a 3rd runway was always precarious not to mention that the government stamped on a lot of people's rights and indeed the law to ram it through.
Sorry you're suffering from the results of the economy though. Unemployment is indeed lousy, however I'm not sure how the blame can be pushed at ConLib just yet - they're doing what most people wanted them to in this case.
