(NBC) - Dawn-Marie Souza worked for American Medical Response, an ambulance company.
Someone complained about her work. Officials say the company denied her a union rep. So she went home and complained about her supervisor on Facebook, prompting a lot of other complaints from co-workers.
Then, the company fired her.
NLRB Acting General Counsel Lafe Solomon said, "The National Labor Relations Act makes it unlawful for employers to interfere with that communication."
The National Labor Relations Board says the firing was illegal. That employees who talk about their work conditions, in person or online, are protected.
NLRB Regional Director Jonathan Kreisburg said, "She was on her own time, on her own resources and that's really what makes the case different."
AMR's policy prohibits employees from making negative remarks about the company. Labor attorneys say the problem is on social media. It's not like chatting with co-workers in the breakroom. Everyone's listening.
Employment Lawyer for McGuireWoods, LLC Keith Dorman said, "Potentially customers, people who might have availed themselves to this employer's services but now we're going to think twice because they saw this Twitter or they saw this Facebook posting."
A hearing is set for January 25th.
