In Azerbaijan, the trade union movement in the field of oil dates back to the 90s of the XIX century. In 1904, the first ever collective agreement between Baku oil workers and employers, called the "Fuel Oil Agreement," marked the beginning of the trade union movement in the oil industry of Azerbaijan. Today, 98.5% of SOCAR employees are members of the Union of Oil and Gas Workers of Azerbaijan. In total, the union of oil and gas workers unites 63,580 members in its ranks.

The Supreme body of the Union is the Congress and is convened by the Assembly (with the exception of exceptional cases) no later than 5 years later. The supreme body of the union in the inter-entry period is the Meeting, which is held at least once every 6 months. During the intersessional period of the meeting, the Presidium, which is the executive body of the union, is convened at least 3 times every 1 month.
