In a dramatic escalation of Nigeria’s ongoing energy and labor tensions, the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) has directed its members to **immediately suspend all gas and crude oil supply to the Dangote Petroleum Refinery**. The directive, issued on September 26, 2025, intensifies an already fraught standoff between the nation’s largest private refinery and its workforce — with serious implications for national fuel supply, foreign exchange stability, and downstream operations.
What triggered the shutdown?
The union’s move is a direct response to the **mass dismissal of Nigerian unionized workers** at the refinery, many of whom were reportedly replaced with foreign personnel, primarily from India. PENGASSAN has accused Dangote management of engaging in “misinformation and propaganda” and failing to engage meaningfully with the union’s concerns.
In its letter, the union instructed that **“crude oil supply valves to the refinery should be shut”**, and that loading operations for vessels heading to Dangote should be halted immediately. It also called upon chapter chairmen across major oil firms to monitor and report compliance. ([Reuters][1])
This drastic action arrives just days after Dangote announced that it would **cease petrol sales denominated in naira**—a move directly tied to crude supply shortages and foreign exchange mismatches.
This dual development—supply cut and currency-limited sales—suggests the refinery is under operational strain on multiple fronts.
Broader implications: Fuel crisis, currency pressures, and union disruption
Fuel supply and domestic prices
With crude and gas deliveries now ordered shut, the risk of **domestic fuel scarcity** looms large, especially given Dangote’s pivotal role in Nigeria’s refining landscape. If the situation persists, downstream marketers might be forced to source imported refined products, likely priced in dollars, which could push **petrol prices upward**. The move could also further weaken the naira as demand for foreign exchange increases. ([Reuters][2])
Foreign exchange & naira stress
Dangote's recent suspension of petrol sales in naira reflects the **imbalance between dollar costs for crude supply and naira revenue from local sales**. ([Reuters][2]) With the union now halting crude deliveries, the gap may widen. The ripple effects could place **additional pressure on foreign reserves and accelerate naira depreciation**.
Labor rights, legitimacy, and precedent
PENGASSAN’s assertive stance is a signal to employers in Nigeria’s energy sector: mass retrenchments without negotiated processes will not go uncontested. The union has publicly aligned with the Nigeria Union of Petroleum and Natural Gas Workers (NUPENG), warning that continued resistance to unionization at Dangote may provoke coordinated industrial action. ([Nigerian News Today][3])
The refinery’s management faces not only logistical and commercial risk but also **legal and reputational exposure** if worker rights are seen as being undermined.
Crude supply challenges and prior conflicts
This supply cut is not occurring in a vacuum. Dangote has long struggled to secure stable crude allocations. Some recent context:
* Earlier in 2025, Dangote halted petrol sales in naira, citing that sales volumes in naira had exceeded its crude allocations. ([Reuters][2])
* The refinery has also undergone a round of **mass layoffs** (exact numbers undisclosed), purportedly for reorganization and efficiency gains. ([Reuters][4])
* The **Federal Government and regulators have threatened sanctions** on oil producers who divert crude meant for domestic refining. ([Reuters][5])
* In 2024, PENGASSAN had already urged the government to increase its stake in Dangote Refinery from 7% to 45% to guarantee national influence over operations. ([The Guardian Nigeria][6])
* PENGASSAN has in the past accused the Nigerian National Petroleum Company (NNPC) of being hamstrung by crude tied as collateral for loans taken during the Buhari era — constraining its ability to supply domestic refineries. ([meteor.ng][7])
Those underlying challenges have created the conditions for today’s standoff; the union’s latest action may be its sharpest demonstration of leverage yet.
What happens next — scenarios to watch
1. **Negotiated settlement**
If Dangote and PENGASSAN return to the table, a truce may be reached. But that would require guarantees on rehiring, union protections, and transparent governance of supply flows.
2. **Prolonged shutdown**
Should the disruption last, Nigeria may see **fuel scarcity, inflationary pressures**, and growing public discontent. The union may extend demands to other refineries or upstream players.
3. **Government intervention**
With national stability at risk, the Federal Government may be forced to mediate or even impose directives binding on Dangote, NNPC, or union parties.
4. **Regulatory & legal fallout**
Questions of labor law compliance, union rights, and contractual obligations may lead to litigation or regulatory action against either party.
This strike is not just a localized labor dispute — it is a **pressure point at the intersection of Nigeria’s energy sovereignty, foreign exchange stability, and industrial relations**. The coming days will determine whether the refinery’s promise as a game changer is undermined or recalibrated through urgent diplomacy and realignment.
