When I worked in HR (a short time for a lunatic), I packed up my share of desks for employees. I normally did it after hours and terminations were also done with little notice but at the end of the day. The sole exception was an employee had threatened to kill a coworker and had been released immediately (while I had the coworker in a side office during the dismissal). I have worked for companies who immediately 'lock down' computer access and escort someone to the door after termination or a resignation. It's to prevent tampering with company product or gather information for a competitor. As a secretary, I actually had it happen to me and they loved me. I was resigning because they were going under and they had actively encouraged me to look around. But the boss explained it best - They'd miss the candy and my comments, but figured I'd be useless for the 2 weeks and they needed the cash. They actually let me finish the day since my boss would have been lost without my straightening out the desk, but all my shredding and trash went to HR with notes. Best advice? Go in rational, try to keep calm. Easier said than done, but hold your head high, explain your mistake and thank them for the opportunity to work there. The gossip mill will be churning and the eyes will be watching. While you're off today, you might want to look into unemployment laws in your state. See if you can file and see what they can say to any future employers.
