It is very common for large companies to suspend an employee with pay pending investigation. It gives them hope and keeps them calm until they can get them out of the building.
I was suspended once. It's no vacation. It's more like "Oh. my God, what have I done? What am I going to do?" 110% stress until you get a decision. If they do decide to let you go they notify you by certified mail. If necessary a couple of security guards will meet you at the gate and escort you in to clean out your desk.
In my case I got my job back but it was the worst time of my life.
I’ll bet that you aren’t a Commie working for ABC.
