Hard up workers are venting their fury at the Olympic stadium site today - demanding more British construction workers be employed at the site.

The Olympic Delivery Authority claims 70% of the workforce is British or Irish yet attempts to scrutinise the figures have allegedly been blocked.

Nearly 400 GMB and Unite union members are also calling for workers to be employed directly and not through job agencies.

'Social dumping of EU workers'

Keith Gibson, from the GMB union, said:

"The protest is about the EU legislation regards to social dumping of European workers throughout Europe in different parts of the country.

Demonstrators are being supported by staff from the Lindsey oil refinery in Lincolnshire, scene of the 'British jobs for British people' protests in late January.

EU posted directive

Gibson added they would lobby MPs in parliament, to discuss the Posted Workers Directive and "the blacklisting that is operating in our industry".

The EU Posted Workers Directive allows a European company to employ its own staff on a temporary projects in another EU member state as long as it's for a limited time and the company abides by local working conditions.

'Local' work force - Figures "massaged"

Last week the mayor of Newham added to concerns that locals are missing out on the job benefits of the Olympics.

More transparency was demanded over Olympic Delivery Authority claims that 20% of the 2012 work force was "local".

The Olympic Delivery Authority claims it had been advertising jobs first in local job centres.

An ODA spokesperson said:

"We are providing jobs and training at a difficult time for the economy, exceeding our targets on the employment of local people.

"We work closely with the UK Borders Agency to ensure all those working on site are legally entitled to do so.

Last year MP for Hackney North & Stoke Newington Diane Abbott accused developers of "massaging" job figures and rubbished claims by the games organisers - who boasted that a quarter of workers would be locals. She called those numbers "regrettably low."

Workers 'brought in from Europe'

Ms Abbott says constructors are bringing workers in from the continent, housing them in hostels and classifying them as 'local.'

She said in the House of Commons:

"One way in which the big contractors are getting round and massaging the figures for local labour is by bringing labourers from all over Europe into the Olympic boroughs and putting them in hostels.

"Those labourers are then counted as local people, but in fact they have been shipped in from all parts of Europe."

Officials "blocking scrutiny"

Sir Robin Wales said that 2012 officials were blocking attempts to put the figures under scrutiny.

He wants to know how many of the 4,101 employees have long term residency in the five Olympic boroughs. Newham has an unemployment rate over 9%.

Figures for foreign workers were omitted - at last count; they made up a third of all workers.
