Petroleum tanker drivers have threatened to withdraw their services starting Monday until the National Petroleum Authority (NPA) addresses their concerns.

According to the drivers, they have consistently raised concerns over their working conditions which have been ignored by authorities.

According to them, the only reason for them to return to work was for the NPA to ensure the full implementation of the Petroleum Producers Transportation Delivery Retail and Loss Control manual, which was formulated by the Energy Commission in 2004.

The tanker drivers further explained that not implementing the guidelines stipulated in the manual was having dire consequences on them, as their salaries and remunerations are not paid by transporters.
