Teli, a California native who grew up in Gwinnett, told The Atlanta Journal-Constitution on Friday that she feels the note is in reaction to Donald Trump's victory in the recent presidential race.
“I feel children feel safe making comments that are racist or sexist because of him," she said.
The note left on Teli's desk comes amid reports from around the country about hate-fueled incidents rising after Trump's election. Locally, a DeKalb County teacher is under investigation after a post-election tirade in class about illegal immigration.
Gwinnett County Schools spokeswoman Sloan Roach said Friday that the district was "doing all it can to identify the person who wrote and left this note." A GCPS spokesman said Monday afternoon that there were no new developments.
On Saturday, Teli wrote on Facebook that her coworkers and the school system had "been amazing in their response to this."
"They have voiced anger and have been tirelessly working to identify who sent this note," she wrote. "I have full confidence that they are taking the appropriate steps to handle this matter."
