The TUC Congress meeting in Brighton has called for a day of action against blacklisting.
A motion passed at the congress called for a Leveson-style public inquiry into the blacklisting of trade unionists. It also called for blacklisting to be made an imprisonable offence.
Justin Bowden from the GMB union argued firms involved should not get any more public work until they apologise and give compensation.
The culture of blacklisting reads like “a low-budget spy film script,” Unite union assistant general secretary Gail Cartmail added.
On Friday of last week construction firm Balfour Beatty reinstated rank and file electrician Stewart Hume. Stewart was part of a successful battle earlier this year to stop the Besna attack on terms and conditions.
He had been made redundant from the Grangemouth power station project the previous week, despite managers admitting there was plenty of work.
Rank and file electricians described the sacking as a “declaration of war”. They threatened protests at every Balfour Beatty project in the country if he wasn’t reinstated.
Meanwhile, electricians protested in Sheffield and London last week against attempts by Crown House to pull out of their national JIB agreement.
Voting is currently under way for Unite construction workers on a pay offer of 1.5 percent. A no vote can act as consultative ballot for strikes against the pay offer.
