Not only that, but as someone who has been through this in the past...
What happens is you find out your department or wing of the building is next. You continue to try to do your job, meanwhile your manager starts walking towards you and stops at a couple cubicles down from you. You breath a slight sigh of relief. Meanwhile you and everyone else is prairie-dogging as others in the office start getting called out, and the VP strolls by and yells at everyone to "have some respect and quit gawking, get back to work". So now you keep your head down, and eventually get a tap on your shoulder from your manager.
You can't help but fight back tears, as you get lead to the conference room where an HR drone explains the package, benefits, and next steps. You are handed a box, escorted back to your desk, and put your personal belongings into the box while being watched like a hawk to make sure you don't do anything stupid. Some things you aren't allowed to put in the box until they are thoroughly examined. A forever half finished document is on your monitor. An email you were about to reply to is still visible, and will go unanswered. Your laptop is shut down, your accounts already locked.
Now you start on the walk of shame carrying the lonely box out to your car, start driving, and then your family wonders why you are home from work so early. But the look on your face tells the whole story, with the look of concern on your wife's face and the look of horror from the kids (of course, being kids, they start asking questions about how this will affect them). "Hey, kids, looks like we will be taking that camping trip a bit early, got some saved up for it, will figure out tomorrow when it gets here. It will be alright."
