An administrative law judge has backed a decision by the Lake County superintendent of schools to fire a teacher who posted what the judge described as “lewd and offensive material” on the TikTok social-media network. Judge Robert Telfer III on Friday issued a 26-page order recommending that the Lake County School Board terminate the employment of Todd Erdman, who was a faculty member at Umatilla Middle School. “During the summer of 2019, and prior to the start of the school year in August 2019, Mr. Erdman created videos with his smart phone using TikTok. According to the document, Erdman lip synced to audio that was sexual in nature in the TikTok posts. “Further, the TikTok videos … ultimately made their way into the public sphere, and students, parents, and school district personnel viewed and became aware of them,” the judge wrote.
