I've always given notice, but over time its been much more acceptable for employers to lay people off without notice/let people go without notice/walk people who give notice - in that environment, I feel no loyalty, nor obligation to give notice myself. It's also perfectly acceptable to quit without notice in the first two weeks of work. Quitting because of severe malfeasance on the part of the employer is also somewhat obviously OK.
