A leading engineering company in Peterborough and Stamford has warned that up to 50 jobs are at risk.
Cummins Generator Technologies has begin consultations with staff at its sites in Peterborough and Stamford.
The company has stated it is considering the job losses because of 'increasingly challenging global economic conditions'.
The announcement is part of a global programme in response to a tough economic climate in key Cummins' markets.
Directors say they need to take measures to cut costs and increase efficiencies to ensure the company can offer competitive products and position itself to emerge stronger when markets recover.
A spokesman said: "This is an extremely difficult decision to begin consultation for possible redundancy affecting a limited number of roles at our Peterborough and Stamford sites.
"We recognise the uncertainty that this process will create for our staff, and ill seek to provide as much support as possible for any employees that are affected.
He added: "However, as a business it is critical that we are able to respond to changing market conditions, and consistently strive to improve competitiveness, in order to strengthen our position when markets return to growth.”
Two years the company announced plans to shut its facilities in Barnack Road, Stamford, and create a technical centre of excellence at its site in Ryhall Road in the town.
Cummins employed 500 people in Stamford and said the the new investment would safeguard the jobs of 150 people.
The company also has offices at Lynch Wood, in Peterborough.
Cummins has had operations in the UK for more than 50 years with eight manufacturing facilities, employing 4,500 employees across 23 sites.
