The sad thing is, it's because of crap like this that a Lot of the large multi nationals are thinking about pulling out of France completely,
The unions are causing more damage that help,
I currently work for a large Multi National and we are in the process of Downsizing, except in France, where the union is blocking the lay off of 20 people, the end result is we have decided to pull out of France completely, so in place of 20 people being laid off, 63 will be out of work in July, I know the layoffs suck, But the union has won again!
