Members of the Blacklist Support Group are joining forces with local electricians to stage the protest outside Balfour’s office in Glasgow.
Event organisers are currently drumming up support for the demonstration online.
Rank-and-file leaders urged: “Spread the word – lets make this a big one.”
Balfour was one of the contractors caught-up in the blacklisting scandal and protesters have lodged complaints with the Chartered Institute of Personnel and Development about members of the firm’s HR department.
