Striking British energy workers could be heading back to work amid reports a deal has been reached to resolve a dispute over the use of foreign labour.UK media reports say union leaders are urging an end to industrial action that swept the country in the wake of a row at a refinery in eastern England. Anger erupted there over the use of Italian and Portuguese contractors, amid claims that British workers were being discriminated against. It comes after a multi-million euro contract at the refinery, owned by oil giant Total, was awarded to an Italian firm. Under a renewed offer to unions, Britons are now expected to be given more jobs at the Lindsey refinery. Workers will vote on the proposals tomorrow.
