For over a decade, the Department of Labor has interpreted Sarbanes-Oxley Act of 2002 as protecting employees of public company contractors.  This was disputed by the First Circuit, which found in 2012 that Section 1514A only protects public company employees.  However, on March 2, 2014, the United States Supreme Court, in a divided decision, confirmed that Section 1514A does, indeed, extend protection to employees of contractors of public companies.
