Electrician blacklisted for raising safety fears

Steps are to be taken to eradicate the illegal blacklisting of workers in Wales who are trade unionists or who raise health and safety concerns.
The Welsh government is to tell public sector bodies how to exclude companies that blacklist when recruiting staff.
Wales is the first UK country to try to stop the practice, where people are denied work because of their trade union membership or union activity.
In February, more than 100 workers in Wales were found on an illegal building industry blacklist.
George James recently found out he was on a blacklist after raising safety concerns while working as an electrician at a chemical works in Baglan Bay, Port Talbot in the 1970s.
He spoke to BBC Wales' Economics Correspondent Sarah Dickins.
