Hundreds of workers at Cummins in Stamford might be taking industrial action over the way the company are dealing with redundancies.
Earlier this year the engineering firm announced they want to close their Barnack Road site next year, putting 300 jobs at risk.
However, 150 workers could be moved to another site at Ryhall Road.
The Unite union say there's been no proper consultation from Cummins about the job losses.
Its as the bosses have refused to meet with the union’s national officer for engineering, Linda McCulloch to discuss the workers’ future.
Unite national officer Linda McCulloch said: “The workers feel deeply betrayed by the company and have little faith in the management when it comes to the future of the Ryhall Road site.
“The ‘transition’ deal was accompanied by threats and bullying that if the workforce did not accept the package, the number of workers at Ryhall Road would be cut to 90 from 150. This completely unacceptable threat has now been withdrawn.
“There has been no real consultation and the company has refused to meet with senior Unite officials. The management’s behaviour is not what you would expect from modern employment relations in 2017, especially when the future of some 300 workers and their families hangs in the balance."
A spokesperson for Cummins said: “Consultations with our staff are ongoing, and as such, we cannot comment about the specifics of our discussions or how they are progressing. However, our first priority is to support our staff through what we know is a difficult period."
"As such, we are taking every effort to engage with our staff and to listen. This includes being open and available for discussions with Union representatives and other stakeholders, and we will continue to be so throughout the consultation period and beyond."
He added: “This has been a difficult decision, which has been driven by the fact that despite everyone’s efforts, the Barnack Road facility remains uncompetitive. It has not been affected by Brexit or the performance of the UK economy.”
Workers will vote on taking industrial action before Christmas.
