You have a family in Redcar. Your children are in school
Quite. Most EU migrant workers going to Lincs. were young and single. Many of Redcar's unemployed are mature people with families and homes (some owned, after 20-odd years earning in the steelworks before it closed), who are much less mobile.
Another factor is (or rather, at the height of labour migration from the EU, was) the ability to save up money that would be worth a lot more back home. A lot of the people we are discussing came here quite willing to live in cramped and ropey digs (which can be quite fun if you are young, among friends and know it is temporary) for a while before going back home with pounds that could be exchanged for a lot of their local currency. That incentive does not apply to the UK-based unemployed.
Another disincentive is the difficulty of getting housing benefit and social housing, which makes those who have it nervous of moving and therefore giving it up, for fear of a worse struggle getting it back again.
Many unemployed young people from Redcar have in fact migrated for work, but those I know have gone to London, Manchester, etc, in roles like nursing, retail management and plumbing, not farm work in Lincs.
