Around 50 workers at a Grimsby petroleum contractor are staging strike action outside Immingham Docks amid claims of a ‘dismissal disgrace’. GMB union said staff at Immingham based petroleum contractor Briggs Marine are taking industrial action, starting today Monday, March 9, following a dispute with bosses.
A picket line has been set up outside the site, on Queens Road, with union members waving flags showing the GMB union logo. The company – which operates one of the UK’s largest petroleum product terminals at Immingham Docks – is being accused of dismissing employees outside of due process.
Workers on the ground at Briggs Marine claim the company is bringing in a replacement team from outside the area to continue operations during the strike. Staff have described the move as “appalling” and say it undermines the industrial action and their safety.
Briggs Marine has been contacted for comment. The rolling strike action will see GMB members outside the Briggs Marine site every day and around 50 union members are expected to take part.

Andy Groves, GMB organiser, said: “Briggs Marine bosses have been playing fast and loose with our members jobs for too long. The UK needs its petrochemical workers now more than ever, for this company to dismiss workers without any due process is a disgrace.
“These workers handle some of the most important petrochemical products, from aviation fuel to the essential products required by UK industry. The company is citing financial motivations as the driving force behind its decisions, but giant Ministry of Defence contracts and an upsurge in demand point to this being about taking on these workers and their Union.
“Company top brass need to participate in the resolution to these issues, get round the table and treat these workers with respect – and quickly!”
It is not the first time that workers at Briggs Marine – which handles imports and exports of vital fuels from across the world – has staged industrial action. This week’s walkout comes over three years after union members at the oil terminal went out on strike following a pay offer below inflation.
In October 2022, members of the GMB Union voted “overwhelmingly” for industrial action after receiving what they described as and “insulting” pay offer deemed to be a “kick in the teeth” amid the cost of living crisis.
