It's not a dichotomy between "no layoffs, no layoffs, please leave the building and never come back" and "There maybe will be layoffs but we can't tell you if you're in them or not" - in both cases the problem is the lack of knowledge. The company could also just give workers notice. Works fine here in Europe.
