 Section 405 protects employee "whistle-blowers" by forbidding discharge, discipline, or other forms of discrimination by the employer in response to an employee's complaining about or refusing to operate motor vehicles that do not meet the applicable safety standards.Congress also recognized that the employee's protection against having to choose between operating an unsafe vehicle and losing his job would lack practical effectiveness if the [481 U.S. 252, 259] employee could not be reinstated pending complete review.The longer a discharged employee remains unemployed, the more devastating are the consequences to his personal financial condition and prospects for reemployment.
