Earlier today, the workers had gone on an indefinite strike against the proposed deal with India to jointly operate the strategic oil storage facility at Trincomalee port. The strike had crippled fuel distribution and resulted in long queues at filling stations across the island nation.
CPC Managing Director Nadun Fernando said: "Disruption in fuel distribution has been reported due to the strike and long lines of motorists have been observed at filling stations."

Lanka Indian Oil Company (LIOC) had said its operations continue despite the strike launched by CPC.
The workers have three demands which include getting the government to stop granting outright ownership of some 14 World War II-era oil storage tanks in the eastern port district of Trincomalee.
The Petroleum Joint Union Alliance had said it opposes the proposal to transfer operations rights to oil tanks to India since the agreement would benefit the Lanka IOC, Indian Oil's subsidiary, allowing it to expand further and the CPC, which is already in debt, will incur further financial losses.
