Communications union Connect is to merge with Prospect, creating the UK’s largest managerial and professional union.
The merger would provide the union with 124,000 members across the private and public sectors.
As much as 80 per cent of Connect’s 19,000 current members voted in favour of the merger.
Connect represents staff in the telecoms industry, including BT, O2 and Vodafone, while Prospect represents engineers, scientists, managers in agriculture, defence, energy, environment, heritage and transport.
Connect general secretary Adrian Askew said: “I am delighted that our members have strongly backed plans to merge with Prospect.
“This merger will help us to realise our vision of creating a union to protect and represent our professional members throughout their careers, with their union membership as a vital part of their career plans.
“We share Prospect’s commitment to focus on the issues that really matter at work, working proactively with our members and their industry to shape the future of the world of work.”
Prospect general secretary Paul Noon said: “This is a great result and confirms Prospect as the UK’s fastest growing union. Our strong focus on Prospect as a professional union for professional people has been shown to have wide appeal.
“This year alone we have seen nearly 25,000 new members join us, ranging from telecommunications specialists in Connect to aircraft safety engineers in the Association of Licensed Aircraft Engineers and public sector workers in the Jersey Civil Service Association.”
