In Section 218 (d) (4) of the Pension Coverage Class Act, all workers in positions under the same pension plan on the date of the State Agreement, all employees in positions under that plan after that date, and all employees in positions that were under the pension plan prior to that date and who had not previously received coverage. , defined as a separate coverage group. (To obtain coverage under a state agreement in which a pension plan covers employees of more than one company, the system can be distributed so that coverage is separated for each business occupied.) Section 218 (c) (2) states that, in the case of each coverage group to which the agreement applies, the agreement must include all services other than those that may be excluded from the state`s choice under Section 218 (c) (3) and (5) and services that must be excluded under Section 218, point c).6). Because the pension coverage group is defined for positions covered by a pension plan, it must include all workers whose positions are below the systemic plan, whether or not those workers are actually members of the plan. From 1951, states were allowed to enter into voluntary agreements with the Confederation to grant social security to public officials. These agreements are called „Section 218 of the Agreement.“ All 50 states, Puerto Rico, the Virgin Islands and other intergovernmental instruments have Section 218 agreements with the SSA. All states, including the 50 states, Puerto Rico, the Virgin Islands and some 60 intergovernmental instruments have entered into an agreement with SSA under Section 218. These agreements allow states to grant, if they wish, Social Insurance and Medicare (MEDICARE) or Medicare for public sector employees. In a letter to the State on February 21, 1962, the Social Security Administration indicated that the proposed coverage would apply to all positions covered by the TIAA and that this coverage could include persons who do not personally meet the requirements of the TIAA. In May 1962, the University of the Social Security Administration sent copies of amendments to the university`s statutes and regulations, which provide that „for persons in positions under the insurance of teachers and the Association of America, the university provides to old age and survivor insurance a sum of each other`s time, which is required from time to time by the federal social security law.“ In addition, the Governor`s confirmation of the results of the referendum, in accordance with Section 218 D) (3), indicates that it was voted on the issue of the inclusion in the state agreement of the services provided by workers in positions covered by the TIAA. These documents show that the State indicated that the coverage under the agreement applied to all workers in TIAA positions and was not limited to members of the plan. An agreement under Section 218 is a voluntary agreement between the state and the Social Security Administration (SSA), which provides coverage for Social Insurance and Hospital Insurance (MEDICARE) or Medicare HI-only for employees of the state and local authorities.
