Charles Simon explained to Le Point that he has been receiving his wages, including annual bonus payments, for the past 12 years after being sidelined by his bosses.
He claims that whilst working for a subsidiary of SNCF he raised his concerns about fraudulent practices that were costing the railway company millions of euros a year.
He was told that another position would be found for him, but 12 years later he is still sat at home waiting for his new post, yet still receiving his wages.
Charles Simon says he has written to the SNCF chief executive but heard nothing, and decided to go to the press now so that the situation can be resolved.
SNCF said that Charles Simon is still an employee.
