Companies who blacklist workers should be barred from winning lucrative contracts such as the A9 dualling programme, activists claimed at a protest in Stirling.
Members of the Unite union, blacklisted workers and other campaigners gathered outside East Central Hub on the Castle Business Park, the joint partnership between public and private-sector organisations which delivers local services.
Union organiser Billy Donohoe said blacklisting was “illegal, unethical and immoral” and described the East Central Hub as “part of the jigsaw” in awarding contracts.
The aim of the campaign is to name and shame companies who blacklisted workers they claimed were troublemakers.
One of the most high-profile victims of blacklisting is Frank Morris who was working as an electrician on the £15 billion London Crossrail link, Europe’s largest construction project.
After raising health and safety issues he believes he was blacklisted and says he is now virtually unemployable. New laws were passed in 2009 but Unite believe the problem persists.
Mr Donohoe said the campaign believed the best way to hit offenders was to ensure that they suffered financially.
“There are a lot of lucrative contracts such as the A9 dualling, the Forth bridge, school construction: we want to make sure these companies are not awarded work.”
