but they're in Europe, not in the UK. We need easy access, so if we leave UK, we're not going far.

The Sun predicts Leave will win. I know, it's the fucking Sun, but they've not been wrong in any election or referendum vote since the 70's apparently. I read that on Twitter so take it with a grain of Twitter, but still. There is obviously a huge groundswell of support for Leave as you say, and in that I don't know ANYONE who supports Leave (anecdotal of course but still!), I have to assume that the Leave group and I have very little in common.

My spouse also works at an international company with head offices in the States. It will absolutely affect every company in that situation IMO. And I believe that effect will be felt far before any of the actual changes to policy come into play. The economy is going to react. FTSE was down by over 100 points yesterday. This is SUCH a stupid idea.

Re: your children, unless they were hoping for jobs as builders, rubbish collectors, house cleaners, or carers, it's unlikely the Eastern Europeans are taking jobs they really wanted, isn't it? I'm glad they can see the bigger picture.
