Hundreds went on strike today (Wednesday, December 7) at an oil refinery and similar sites over working conditions. Construction workers took wildcat strikes and protests at locations in London, Cardiff, Glasgow, Hull, Lincolnshire, London, Manchester and Merseyside this morning. Union members when balloted had voted 80% in favour of strike action. Employers Balfour Beatty Engineering Services challenged the walkout and a re-ballot was ordered by the trade union. Glasgow saw protesters stood outside the headquarters of Balfour Beatty Engineering Services.
