According to the Ministry of Labor and Social Affairs, the Czech pension system is defined as a two-pillar system. The first and by far thickest pillar is the state pension system, which is paid into by all employed citizens and foreigners working on a full-time basis. It is termed pay-as-you-go, but rather than those funds being used for the future pensioners, as is the theory, the demands of the present pension system draw on those funds.
