The Burlington Northern Santa Fe Railway Company (BSNF) was formed on December 31, 1996 when the Atchison, Topeka and Santa Fe Railway and Burlington Northern Railroad merged into one. It is the second largest rail system in the United States behind Union Pacific. It owns and operates tracks in 27 states, primarily in the Western and Midwestern states, and a small amount of tracks located in Canada. Due to the complexity of the business, Burlington Northern Santa Fe Railway is divided into 14 different divisions. These divisions are then repeatedly broken down into smaller subdivisions. All of this was done to help with what could easily become a logistical nightmare. However, it was not a logistical nightmare, but a brief but influential legal nightmare that ended up happening in early 2001 to the Burlington Northern Santa Fe Railway Company. The Burlington Northern Santa Fe Railway was asked by the US Equal Employment Opportunity Commission (EEOC) to "stop testing its employees for genetic defects as part of a settlement against workplace discrimination." (Schafer, 2001) This is a result of over 30 employees being tested without their knowledge or consent that genetic testing was being conducted using some of their blood samples provided during medical visits. This is the first case brought against a company and is a groundbreaking case when it comes to genetic testing. The medical visits were conducted as a direct result of employees complaining of possible carpal tunnel syndrome (CTS) due to the repetitive work they were performing in conjunction with their job or occupation. The ailments did not stem from previous medical problems as the company was secretly trying to find out. These complaints came from the worker after many years of work. The repeated pressure and movement endured in their wrists while performing their specific occupation has caused many of them undue pain and suffering over the years. The company decided to send these employees for medical visits using its own doctors. The company asked that [doctors] draw extra vials of blood to test for possible prior genetic links to carpal tunnel syndrome. They were trying to link it to their employees' genes rather than accepting that the employees had contracted the injuries while working with the company.
