Management and HR purposely blindsides you so your not prepared. It can happen to anyone at anytime.
That doesn't mean fight it or make a scene. It just means think about how you would respond if you are unexpectedly called into your managers office and told you are underperforming and no one likes working with you.
What would you say? Getting hostile does you no good in fact they may be counting on it.
Also, what will you say when they give you a set of impossible goals the CEO couldn't even achieve.
That's how it works. At least have a plan.
