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 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. Ensuring the eventual recovery of backpay may not alone provide sufficient protection to encourage reports of safety violations. Accordingly, 405 incorporates additional protections, authorizing temporary reinstatement based on a preliminary finding of reasonable cause to believe that the employee has suffered a retaliatory discharge. The statute reflects a careful balancing of the relative interests of the Government, employee, and employer. It evidences a legislative determination that the preliminary investigation and finding of reasonable cause by the Secretary, if followed "expeditiously" by a hearing on the record at the employer's request, provide effective protection to the employee and ensure fair consideration of the employer's interest in making unimpaired hiring decisions.
