The New Jersey Conscientious Employee Protection Act (CEPA) protects whistleblowers who speak out about their employer’s potential legal violations. www.nj.gov. CEPA prohibits employers from retaliating against employees who have complained about a practice that the employee reasonably believes is unlawful or indisputably dangerous to the public health, safety or welfare. Several federal whistleblower laws also protect employees from disclosing fraud such as the False Claims Act.
