What is the ruling on paying an employee at an insurance company a sum of money in exchange for him signing off on papers for receiving salvage from accident vehicles, knowing that the salvage is complete?

The work the questioner is tasked with involves two prohibitions: The first is aiding in sin, because the work of a commercial insurance company is not permissible, according to the Almighty's saying: "And do not cooperate in sin and aggression." This differs from an Islamic insurance company. The second is paying a forbidden bribe to an insurance company employee, because it is not permissible for the employee to take money for his work, just as it is not permissible for the questioner to give it unless compelled, and there appears to be no necessity here.
