ISSSTE was founded on December 30, 1959 by
president Adolfo López Mateos. In addition to ISSSTE, which is exclusive for employees of the federal government, states in Mexico have their own separate health and retirement system for government workers within its own state. For example, the state of
Tabasco offers its employees retirement, health, and other similar benefits through an agency called
Instituto de Seguridad Social del Estado de Tabasco, or "ISSET". In September 2020, former director of FOVISSSTE
José Reyes Baeza Terrazas was accused of embezzling MXN $129 million (US $6.14 million) as part of the '''' ("master scam") scandal. == Criticism ==
