I think it's about 5 people, I do not work there but that's what I heard. There are many reports in the media about this. The severance pay is three weeks for every year that you worked there, I think it maxes out at Six, that's all what I heard so far - I think they will continue to do this as there is less work and they need to get costs under control.
