The Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) is one of the 24 Senior Staff Associations in Nigeria. It was formally registered as a Trade Union on 15th August, 1978. The Union has come a long way since then. Despite the debilitating interregnum of military take-over of the union from 1994 - 1998, it has risen like the proverbial phoenix from the ashes of oppression and harassment by the military dictatorship.

PENGASSAN has continued to be in the vanguard of protecting the rights of its members and promoting harmonious industrial relations between its branches and the various managements on one hand and the government on the other. We must speak not only for our members but also for the Nigerian people.
