Union says 57-year-old who set himself alight in Merignac had struggled with frequently having to change jobs

A France Telecom-Orange worker has died after setting himself alight outside his office, the latest in a wave of suicides at the company. The 57-year-old married father of four, described as a sociable member of staff, set himself on fire in the car park of a site at Merignac, near Bordeaux, after arriving for a morning shift.

He had worked for the company for 30 years, most recently at a call centre dealing with company accounts, and was a trade union member who monitored safety and work conditions. Paramedics could do nothing to save him.

François Deschamps, of the CFE-CGC Unsa union, suggested the man had struggled with being made to frequently change jobs. "Those enforced changes meant he had to sell his house. He had written to the management on several occasions and in my understanding had no reply," Deschamps told AFP. "I saw him two or three weeks ago. I did not feel like he was on the verge of suicide."

France Telecom is Europe's third largest mobile phone operator and biggest provider of broadband internet services. But in recent years it has become synonymous with death and despair in what management called a "suicide contagion effect".

At least 23 of its employees killed themselves last year, and there were more than 30 reported suicides in 2008 and 2009, as well as many more attempts.

Among those who were found dead at their homes, some had left notes explicitly linking their suicide to their jobs. Unions complained of a climate of bullying, extreme pressure, poor management methods and restructuring cuts that forced people to repeatedly change jobs.

A 28-year-old worker who was found dead in his garage in Besançon in the east of France in August 2009 had left a note that talked of his girlfriend, but also mentioned how he felt "helpless" and "angry" over issues at work. A French prosecutor said it was impossible to formally establish a link between France Telecom and the suicide, but workers held a protest march over his death.

A month earlier, a 52-year-old employee killed himself in Marseille, leaving a note blaming "overwork" and "management by terror". He wrote: "I am committing suicide because of my work at France Telecom. That's the only reason."

Other deaths included that of a 51-year-old who threw himself off a bridge in the Alps after being moved from a back-office job to one in a call centre.

Staff said the climate had worsened since privatisation. Some staff complained of divorce, family breakdown and being forced to sell homes due to random job changes.

Last October an official report found that the plan, begun in 2006, to slim down the company and scrap 22,000 jobs in three months was behind the feeling of distress among staff.

In recent months, the company has increased the presence of psychological support workers and pledged to reduce workplace stress and staff difficulties.

Its former head, Didier Lombard, who had warned of a "spiral of death" stood down last year and was replaced by his deputy as a sign that management was taking the crisis seriously. Lombard had been criticised by unions for his poor choice of language in describing a "suicide trend" at France Telecom.

The former state-owned monopoly was privatised in 1997, although the French government remained the biggest shareholder.

Under government pressure, the company was ordered to put in place measures to monitor and counsel staff thought to be suicidal, and at one point froze 500 employee transfers that were part of restructuring plans.
