Earlier this year the ‘Big 8’ major construction employers announced plans to tear up an industry agreement on pay, grading and seniority which would result in pay cuts of up to 35%. Workers, not trusting the Unite union to act in their interests, organised themselves into ‘Sparks’, an independent rank-and-file electricians’ group run by a committee elected from their ranks. Their scepticism towards the trade union structures appeared to be vindicated when Unite official Bernard McAulay described Sparks as “cancerous” in a leaked email.
