The Interim Public Servants Association in Tonga is planning another march on parliament if an agreement is not reached with the government soon.
Nearly 3-thousand workers have been on striking for almost two weeks in protest at a hefty payrise for senior public servants and calling for raises of their own.
The two groups met this morning in a bid to settle a strike without success.
The Secretary of the Interim PSA, Vuna Fa'otusia, says the two sides remain at odds but they are working hard to come to a compromise.
Mr Fa'otusia says another meeting tonight between the government and PSA is unsuccessful the striking workers will march again.
"Now we are setting up a march to His Majesty on Monday to present our appeal. Hopefully it won't come that far, that's why we have to push this negotiation tonight and even tomorrow."
