The United Nations Pension system is in need of reform. The current system is outdated and unsustainable. The UN pension system is a contributory system, which means that employees and retirees contribute to the system. The system is also financed by investment income. However, the investment income is not enough to cover the costs of the system. As a result, the system is in debt. The UN pension system is also unfair. Employees and retirees do not receive the same benefits. Employees receive a pension based on their salary, while retirees receive a pension based on their length of service. The system is also unfair to women. Women receive a lower pension than men, even if they have worked for the same amount of time. The UN pension system must be reformed to make it fair and sustainable. The system should be based on contributions, not the length of service. Employees and retirees should receive the same benefits. The system should also be funded by contributions, not investment income. This will make the system fair and sustainable.
