In Sweden (don't know where this company is located) it's usual with collective bargain agreement and if you've been employed for along time (5+ years) it's not uncommon with 3 months notice. It is usually accompanied by 6 months if your employer wants to let you go (but it's not easy if you're the employer to let people go). Most of the time, these periods are negotiated when someone resigns though.
