British Gas could face the threat of a strike by thousands of its workers today (Tuesday) when the result of a ballot for industrial action is announced.

Up to 8,000 members of the GMB have been voting on whether to launch a campaign of industrial action over claims of “macho management” at the company.

Most union members voted last month for a formal industrial action ballot.

GMB general secretary Paul Kenny said: “British Gas has turned from being a reasonable employer where people had job satisfaction into one with a culture of bullying, customer exploitation and profits at all costs. This change of culture is very much the result of recent management changes.

“GMB and its members took a conscious decision not to seek an industrial action ballot during the recent terrible weather because our members care about the customers.”
