The president of the Solomon Islands Teachers Association says strike action, which began today, will continue tomorrow if an arrears payment is not received today.
Kendrick Sanga says teachers have been sent a strike notice which won't be lifted unless the money goes into their accounts.
Mr Sanga says SINTA is taking a wait and see attitude with the government which has broken the memorandum of understanding.
"We don't have a meeting or we don't arrange a meeting with the government. We just listen out to them and if they want us to sit down again for a round table they can arrange for that because what we understand here is that they fail to meet out memorandum of understanding."
The threatened strike could affect two thousand Form Five students who are sitting exams this week and next.
