French Labour Minister Xavier Darcos is to meet the head of the country's main telecommunications company to discuss a number of suicides among its staff.
Twenty-three employees of France Telecom have killed themselves since the beginning of 2008.
Unions blame tough management methods at the multinational, which was privatised in 1998.
But France Telecom says the rate of suicides is statistically not unusual for a company with a 100,000 workforce.
According to the World Health Organization, France had an annual suicide rate of 26.4 for 100,000 men in 2008. The rate for women was 9.2 suicides per 100,000.
The latest suicide occurred on Friday, when a 32-year-old woman leapt to her death at a France Telecom office in Paris.
On Wednesday, a 49-year-old man in Troyes, east of Paris, plunged a knife into his own stomach during a meeting in which he had been told he was being transferred.
He is being treated in hospital.
