Electricians were the biggest targets in the blacklisting scandal, with up to a third of those listed working in the trade, according to a new analysis.
Research shows that out of 1,864 people on the blacklist, 529 were electricians.
Labourers made up 240 of the names, with joiners and carpenters a further 211.
In 2009, the Information Commissioner’s Office raided the Consulting Association, which operated a blacklist and filed on more than 3,000 individuals used by more than 40 construction companies to vet individuals.
This information was shared with the unions, to enable them to contact and identify members who appeared on the list.
Paul Kenny, general secretary of the GMB union, who produced the analysis, said the scandal had “widened” to “gross abuse of human rights and of basic freedoms”.
He demanded a full judicial inquiry with the “full glare of publicity”.
“All of those involved need to be brought to account and be forced to apologise and compensate those they damaged”.
