The treadmill was purchased for classroom use.

So Christopher Jones was taken aback when he noticed another staffer at Pine Ridge Elementary School in Stone Mountain loading it into her car.

The school had received Fitbits and Apple Watches through supply wishlists posted on DonorsChoose.org, which purchases items requested by teachers for their classes. Jones said he noticed teachers using those, too.

“I was told we were able to use the items, too,” Jones said recently.

Jones gave the information he had to district officials in early January. Several weeks later, he was put on administrative leave. By the end of the year, the district chose not to renew his contract.

He’s now suing, saying he was retaliated against for blowing the whistle on alleged misconduct.
