Unite members working for Balfour Beatty Engineering Services have voted by a 66% majority to take strike action to stop their bosses unilaterally imposing a new agreement for electrical and mechanical construction workers’ terms and conditions.
They also voted by a 70% majority to take action short of a strike.
BBES workers last voted to strike in December but were forced to take action unofficially after Unite caved in the face of BBES legal threats.
BBES bosses will again challenge the ballot result and will seek a High Court injunction on Tuesday 7 February.
The union says that it will begin ballot procedures at Spie Matthews and NG Baileys, two of the group of seven contractors who, along with BBES, plan to rip up the existing collective agreement.
