Hundreds of redundancy-threatened workers have gathered in Edinburgh to “Battle for BiFab”.
In a rally organised by the GMB Scotland and Unite unions, the workers gathered on the Royal Mile before marching to the Scottish Parliament to demand action to save the firm.
A spokesman said: “The BiFab workers have courageously decided to continue to work to complete their current contract, despite having no guarantee that they will be paid.
“Trade unionists are staffing the gates so that equipment and materials cannot be removed from the Methil yard.
“This is a viable workforce and these are viable yards – important strategic assets – ready and able to help deliver the future of Scottish manufacturing.”
Unions claim the firm’s financial difficulties are a result of Dutch-owned contractor, Seaway Heavy Lifting (SHL), not paying the company for work already completed.
However, SHL maintains it has continued to pay BiFab on time and estimated that 61% of the work had been completed in return for paying BiFab 61% of the project value.
