JOHNS CREEK, Ga. – Fulton County teacher Jennifer Lynch learned a valuable lesson about social media recently: what you post can cost you your job.

That seemingly obvious reality apparently didn’t occur to Lynch as she waited for a disabled student to make up several exams on the last day before winter break and fired off several harsh Facebook posts badmouthing the child, 11 Alive reports.

Officials with Fulton County Schools – “Where students come first” – called Lynch to the human resources department upon her return from break this week to confront her about the posts, resulting in her resignation.

Lynch, who teaches Latin at Johns Creek High School, posted to her 400 Facebook friends Dec. 18 that one of her students “gets an extra hour for each final, and complains he decided to finish all six on Friday afternoon” before winter break, according to the news site.

“Ugh. Thank a lot, kid, for finally coming to finish your effin’ final more than THREE HOURS after school let out and almost TWO HOURS after the principal said teachers could leave,” Lynch posted.

Lynch continued:

“ … To make matters worse, he’s giving regular updates on how many questions he has left. And I’m over here like: (meme with words ‘Look at all the (expletive) I don’t give! They’re falling from the sky’)”

“Holy (expletive). He’s finally gone. I get to go home now. Only 5.5 hours after school let out and 4 hours after we were told we could leave.”

“On the way out, he says, ‘… isn’t it funny? I’ll be the last student to walk through the doors of JCHS in 2015?”

“No. That’s not funny. That’s tragic. Your life is tragic. You’re Romeo and Juliet. I want to be sad for you, but at the end of the day, we’re all better now that you’re not around.”

She also poked fun at the teen’s disability, The Mighty reports.

“He has some (expletive) disorder: one of those ‘we don’t know what his disorder is and we don’t want him to be labeled, so we are not going to find out, but we want academic accommodations anyway’ disorders,” Lynch wrote.

District officials sent out a statement explaining that they don’t typically monitor employees’ social media accounts, but Lynch’s comments crossed the line.

“We are appalled at the social media posts and the disrespect shown to a student,” the statement read, according to 11 Alive. “Ms. Lynch met with our Human Resources Division yesterday (the first day back for teachers) where she was notified that this behavior did not meet the standard of professionalism expected of all Fulton County teachers.

“She decided to resign her position and is no longer employed by Fulton County Schools,” it continued. “FCS does not monitor the personal social media of our staff but employees are accountable for the use of good judgement.”

Fulton County schools does not have a social media policy for employees, but middle school teacher turned consultant Candance Ledetter told the news site Lynch should have known her comments wouldn’t fly with her employer.

“There’s no reasonable expectation or explanation for using profane language like that, especially when you are not only representing yourself but the school you work for,” Ledetter said.

Virtually everyone who commented online believes it’s a good thing Lynch is no longer teaching at Fulton County Schools, though some believe she should be banned from the profession altogether.

“Any teacher who speaks like that shouldn’t have a teacher license,” Christopher Cheney wrote.

“She should never be allowed back in a classroom!” Tamera Cupit added. “Or around any children for that matter!”
