"I understand it's a busy world we live in and you've got to pack it in, but it's beneficial to your whole system to let it go for an hour," Van Ness said. "An hour isn't too much to ask."
Van Ness said she was called into a meeting with her supervisor at Plus One Health Management, the contractor Facebook uses for its onsite gym and fitness programs, two weeks after the cellphone incident.
"They sent me packing, they didn't even want to hear my side of the story," Van Ness said. "They already had my paycheck ready."
The termination letter said the employee complained Van Ness has "made a spectacle of her" during the class.
A Facebook spokesman said the company has nothing to say on the matter since Van Ness was not a Facebook employee.
A Plus One Health Management representative declined to comment.
