The Truck Drivers Union attached to the liquefied petroleum gas (LPG) filling plant of the Indian Oil Corporation at Paripally, near here, has threatened to launch an indefinite strike in protest against the alleged anti-labour stand of the truck owners on the bonus issue.

The drivers went on a token strike on Saturday as the truck owners failed to turn up for talks convened by the District Labour Officer (DLO) on Friday.

The truck drivers are demanding a bonus equivalent to two months’ salary.

They alleged that the truck owners had been consistently taking a negative stand when it came to wages, bonus and other benefits for the employees. Union president Paripally Vinod said that by boycotting the talks called by the DLO, the truck owners were planning to deny bonus to the employees.

The labourers would stand united against this attitude, he said.

It is from the Paripally plant that Indane cylinders are distributed to the districts of Thiruvananthapuram, Kollam, Alappuzha and Pathanamthitta.

Any strike at the plant is likely to affect Indane distribution in these districts.
