Listening to the video now, but this smells wrong to me. Any worker at any nuclear power plant can bring safety concerns directly to the Nuclear Regulatory Commission, and retaliation from the company is strictly forbidden. That is written right into the Code of Federal Regulations, and every worker is educated on it. So far it sounds like a whiny old lady complaining about labor union misconduct. That would have nothing to do with nuclear power as an industry.
This sounds so totally kosher it isn't funny.
