I've spoken to a couple of people who quit their job without providing two weeks notice and weren't sure about the repercussions. With the first one, it shouldn't make much of a difference because the person had only been at the job for a week. I suggested that he not even mention this position when he applies for new jobs.
The other case is more complicated. The woman stayed late at work, cleaned out her cubicle, and left a resignation letter on the desk of her supervisor. The letter apologized for not giving notice (sample resignation letter - no notice) and said she needed to resign immediately.
It would have been wiser, if circumstances allowed, to ask if she could be released from her job early (resignation letter - short notice), rather than just quitting.
The problems are going to arise when she starts a new job search. It's doubtful that she'll get a good reference from the company that she quit without notice. That means she's going to have to do some explaining to prospective employers, and it's always easier to move on when you've left your last position on good terms.
