Construction union Ucatt fired its latest salvo today in its campaign for justice for blacklisted workers.
The union is distributing postcards for members to send to their MPs urging them to sign an early day motion (EDM) tabled by Liverpool Walton MP Steve Rotheram.
Mr Rotheram's EDM calls for "a public inquiry into the blacklisting scandal, the Information Commissioner's Office to inform all individuals who appear on blacklists, companies guilty of blacklisting to be barred from tendering for public-sector contracts, strengthening of existing blacklisting regulations and for blacklisting to become a criminal offence."
Ucatt general secretary Steve Murphy said that the union was "absolutely committed" to winning justice for every single blacklist victim.
He said: "Those involved in blacklisting workers have avoided justice and their actions must be fully exposed.
"The postcard campaign is the latest step in the battle to win justice for blacklisted victims."
He added: "There is growing anger among construction workers, as each new revelation shows the true extent of the blacklisting scandal which is possibly going to be much greater and effect far more construction workers than ever imagined.
"Workers want and deserve answers for themselves and for their colleagues."
The union has printed 10,000 postcards which are being distributed via branches and shop stewards.
Members can request additional postcards by going to www.ucatt.org.uk/blacklisting where details have also been provided about how members can directly email their MP about the issue.
