Tonga's Public Service Association says it is still planning strike action from next Monday and believes a number of government agencies will be forced to close.
The PSA's secretary general, Mele Amanaki, says they want up to 22 percent in cost of living adjustments to be paid over the next two years, with an immediate commitment to at least six percent.
She says this is based on assessments the Government itself has done on public servants' wages going back nearly 10 years and claims by the Finance Secretary that there is no money available are wrong.
She says up to 650 members have agreed to strike unless the Government meets their terms.
We are not including the Ministry of Education in strike action because of the exams of the students. So mostly this is just Ministry of Health and the other smaller ministries. We can close customs, we can close the wharf and the airport.
