James Cartlidge met with bosses at the Delphi Diesel Systems factory in Sudbury on Thursday to discuss the 176 jobs that are to be cut.
The firm is cutting its workforce as it moves towards high precision engineering, outsourcing some of the unskilled tasks performed at the site.
Mr Cartlidge confirmed the redundancies would be going ahead, saying that of these between 80 and 90 would be workers on temporary contracts.
The Free Press recently reported the plight of Delphi temporary worker Harry Scott-Molloy who expressed the lack of security felt by many in his situation.
Delphi has said it hopes the majority of job losses will come from voluntary redundancy, though it is unknown how many workers will take this option.
Mr Cartlidge said the job losses were disappointing but said the change towards highly skilled manufacturing would be a positive if this made the plant more competitive.
“The more competitive the plant is the more chance there is of them keeping the jobs they do have,” he said.
Mr Cartlidge also confirmed that the plant will not be taking on new apprentices this year but hopes to be able to in 2016.
