That is being laid off, not being fired - big difference. Being fired means being let go for poor performance / bad behaviour. No severance or grace period is necessary there (will be written in the contract). Being made redundant, particularly a redundancy of this size is quite well protected in EU. Typically negotiations between HR and representatives of the laid off group are required, you will continue to work (officially at least) until negotiations are over, as you are not officially out yet. This usually takes a few weeks.

I can tell you this from personal experience...
