Walter Cardin was once a safety manager for the Shaw Group (formerly Stone and Webster Construction) while working at three Tennessee Valley Authority nuclear plants. His company collected safety bonuses worth over $2.5 million for his group’s low injury rates. He was sentenced last week to 78 months in prison for major fraud and his company was forced to pay back over $5 million after a six-year investigation revealed that Cardin had regularly provided false information about injuries by misreporting the number and severity of 80 incidents, including broken bones, torn ligaments, hernias, lacerations, and shoulder, back, and knee injuries. Aside from defrauding the government, Cardin’s actions also resulted in injured employees being denied or delayed medical treatment, reduced the safety of the work environment on job sites, and forcing employees to work through medical conditions that created risks of additional injuries. Cardin denied intentionally misclassifying injuries and knowing that safety bonuses were tied to his classifications of injuries, but emails sent by Cardin to this effect as well as paperwork in his desk were uncovered by investigators, proving his guilt.
