This document discusses social security benefits as a type of workers' benefits in human resource management. It defines social security as a program that provides economic security to the public using public funds. The main types of social security discussed are retirement benefits, survivor/death benefits, and disability payments provided by the US social security system established in 1935. Three criteria that must be fulfilled for employee benefits are that they should be computable in money, the amount is not predetermined, and there is no contract stating when the sum is payable. The document also discusses possible changes to social security systems to control future costs, such as higher taxes on benefits, including all government workers, and longer working/later retirement.
