The Solomon Islands National Teachers Association, or SINTA, says a lack of monitoring teachers and where they are posted is a big problem in the country.
The names of about 50 teachers have been removed from Ministry of Education files after a nationwide assessment found their jobs could not be verified.
SINTA's assistant General Secretary, Charlie Pango, says Teachers need to be more honest with Education authorities.
"It's a bad practise. They don't deserve to be paid when they are not doing any teaching at all. I don't know who to blame, but the system is like that here. They are not properly monitored and a lot of teachers are running around the place without properly informing the authorities about where they are. Yeah, it's a real problem here."
