There's a similar pattern among the younger staff, many of whom have been elevated to training positions without any experience or education, Fischbeck added. Like the older staff members, all they know is what SeaWorld's taught them.
"They wholeheartedly believe in it because that's all they know," she said.
SeaWorld's secretive management policies were perhaps best highlighted during the release of "Blackfish" in July 2013 - Fischbeck would voluntarily leave the company that December.
"We actually had a collective meeting before it came out telling us to say it was fake," she said. Employees were also instructed to tell everyone that SeaWorld loved its animals, and to dissuade family and friends from seeing the film.
"They were feeding us lines," she added.
The entire response was "extremely hush-hush," she said, which naturally made her curious. When the film was released, she went to see it in theaters.
"It just blew me away ... like, this isn't false," she said. "I didn't see one thing that was false."
