100,000 gas workers were balloted over strike action as their demand for 10s a week in wages, a 44-hour week and 14 days holiday was denied. The National Federation of General Workers stated that they would announce the results of the ballot soon, which if it took place would mean that gas supplies would be cut off around the country within two to three weeks.
