GE has opened negotiations to trim its staff in France under a "collective mutually agreed termination" agreement, a measure introduced in France in September 2017. An early retirement plan is also on the table, union officials said.

"In a particularly difficult time for the power sector, GE is currently reviewing its businesses to ensure they are best fitted to market reality and ensure their success," the company said.

Some 229 jobs could be cut at Alstom Power Systems (APS), including 146 at GE Energy's European headquarters in Belfort, eastern France, unions said.

Another 149 jobs could go at GE Energy Power Conversion France and 90 at GE Grid, they said.

GE employs 16,000 people in France, including 6,000 in the power branch.

When it bought Alstom's energy business, GE had committed to maintain jobs for at least three years in France and create 1,000 net new jobs by the end of 2018.

The French government brandished the threat of fines in June 2018 after former GE Chief Executive John Flannery told Finance Minister Bruno Le Maire that the company would fail to create as many jobs as promised.

A meeting on that issue is expected to take place at the finance ministry in coming weeks, a GE spokesman said.
