Did some thick mackem sit in the back of your grotty cab and tell you that fuckin bollocks? Who says there's a huge unemployed labour force in Polish shipbuilding? Speaking as some who has worked directly with Eastern European nationals in an English shipyard I can assure you that your informant and you are talking shite. The trouble with UK shipbuilding labour is that all the skills have been lost due to the virtual abandonment of large scale shipbuilding here in the last 50 years. No apprenticeships mean no skills passed on, which means a need for foreign labour. Yes, they're paid less, yes, they're stuffed into houses. But the need for them is fuck all to do with the EU.
