“BRITISH JOBS FOR BRITISH WORKERS” is a slogan that’s become very familiar in the past few months.  Energy sector workers across the country have staged wildcat strikes and demonstrations to protest at the fact that workers have been brought in from outside the UK while local people go jobless.  Now the protests are spreading to the construction industry.  The union Unite is planning pickets and unofficial action at construction sites where foreign workers are employed, and the Olympic site in East London is being highlighted as a high-profile potential target for the campaign.
