It's an interesting claim which at first you want to dismiss but I know someone that works HR for a long time at a major company and they told be about techniques bosses used to try to get rid of certain people and were themselves the target of a similar tactic at one point.
French laws are certainly a lot different than we have here.
What's interesting is that it's not a civil trial but rather criminal.
Not sure what all they did but it was a restructuring and they were shaving 22,000 jobs.
During that time they averaged about 7-8 suicide attempts a year.
Now the French average is about 12 suicides per 100,000 (per google) and about 40% of the employee attempts were not successful...and the company currently has 100,000 workers in France.
So, it would seem that their suicide rate was about 1/3 of the national average.
Big wildcard there would be to find a homogenous comparative group but still, just doesn't seem like a smoking gun there. I mean, they may have tried to be a-holes to employees to reduce headcount because the laws wouldn't let them fire them but the whole suicide thing doesn't seem supported by the numbers.
