I know that feeling, getting back to the grind can be tough. I'm glad you had a nice weekend getaway, it's always a great way to relax.
As far as those people returning to work and forgetting how to use the system or remember passwords. That's ridiculous. I would say they are moron who just don't care either. A monkey could retain some training longer than that. It just goes to show how motivated they are to actually work. And they are teaching the new generation?
