On any Monday morning, the polite thing to do is ask your co-workers about their weekend. For the most part, no one really cares about your weekend. They are asking simply because it is expected on a social level. The expected answers go somewhat like this:
"It was good. How about you?"
"Too short. Yours?"
Or for non-morning people:
"Good. You?"
In almost every business, Monday mornings are packed with everything that needs to get done that week and finishing up things that didn't get done the week before. Unless you're only working with one other person, inquiries about your weekend are not to be taken literally. We got shit to do, son!
Employers want to give off the appearance that they care when they really don't. It's only acceptable to tell someone if something really bad happened or if something really good happened. Everything in between can be summed up in one of the above quoted responses.
Here's one thing you should NEVER talk about--even if you work with your best friend--HERPES. No one wants to know that you had a breakout of herpes over the weekend. That's the kind of shit you need to keep to yourself. It only makes the inquirer uncomfortable and nauseous and it makes you look socially retarded.
Herpes is for life.
