Public servants involved in the protest gathering against the Goods and Services Tax (GST) at Dataran Merdeka in Kuala Lumpur today could be considered as traitors to the government and do not deserve to be called civil servants.

Cuepacs president Azih Muda said civil servants involved in the gathering had violated the "Akujanji" and Service Pledge that they had made.

"I have stated before that civil servants must not get involved in any gathering against the government as they had taken the oaths...so whether they like it or not, they must abide by the rules.

"If they are dissatisfied and wish to take part in such a gathering, they should leave the public sector.

"We aim to make Malaysia a developed nation but such protest gatherings can derail the plan," he told reporters after the Civil Servants Workers Day celebration at Dewan Wawasan, Thursday.

It was launched by Prime Minister Datuk Seri Najib Tun Razak.

Azih said action could be taken against civil servants found to have taken part in today's anti-GST gathering.

"They must not say they are victimised if disciplinary action is taken against them. It's their own fault if they join the protest gathering as I had issued an early statement for civil servants not to get involved.

"The prime minister has always opened doors for Cuepacs to voice our needs and woes and there have been solutions to help us cope with rising costs and to see what more needs to be done in the public sector. So there is no need to participate in the protest gathering."

Azih said at the Workers Day celebration, Najib urged public servants to carry out their tasks with full dedication and most importantly, the prime minister hoped they could help boost national income to mitigate the rising cost living through greater work productivity.
