If there's one thing I know not to do, it's publicly bash my boss on Facebook (not that I ever would!). Some people aren't quite so wise, though with the right lawyers, they can still come out of the experience in one piece. Such is the case for Dawnmarie Souza, who sued her former employer for firing her after nasty comments about her supervisor showed up on Facebook. The case has now been settled, and the company has agreed to revise its policies on workers communicating with one another.

Souza, employed by the American Medical Response ambulance company, was apparently dissatisfied with her supervisor in 2009. She turned to the platform that many of us use these days to vent our frustrations: the Facebook wall. There, she referred to her boss as a "dick" and a "scumbag" in two separate postings made from her home, and soon thereafter, she found herself out of a job.

The National Labor Relations Board took up Souza's case in October of 2010 and filed suit against AMR. In the complaint, the NLRB and Souza argued that she was within her rights as an employee to talk about the conditions of her employment with other coworkers under the National Labor Relations Act. As such, the NLRB accused AMR of illegally firing Souza and denying her union representation, despite AMR's insistence that Souza's comments shouldn't be protected.

The settlement came this week, with AMR agreeing not to discipline employees who are asking for union representation. The company also said it would revise the policy in its employee handbook regarding how employees are allowed to discuss work conditions with their coworkers.

Because this case didn't end up going to court, we'll never know which way the ruling would have gone. However, a student who was suspended after making nonthreatening statements about her teacher on Facebook got the go-ahead from a judge last year to sue her former high school. The cases have their differences—students are often held to a stricter standard than the rest of us—but they both argue that people shouldn't be punished for making mean comments on the Internet during their personal time.

Of course, that doesn't stop employers or teachers from treating you differently if they see you bashing them online. There are plenty of ways to get rid of an employee (or never hire an employee to begin with) without specifically citing his or her Facebook comments, so it's still wiser to keep your unflattering posts to yourself—or at least make sure they're not so public that the whole world can see them.
