The Solomon Islands Teachers Association says it is fighting for the removal of a key education official with the Honiara City Council.
SINTA claims Don Houkura was involved in a number of controversial issues when he was the chief education officer for the Council.
The Association says he was to retire from the role but his contract was extended until the end of last year when the council created a new role for him as education director.
Members of SINTA are now threatening to boycott the start of the school year on Monday until Mr Houkura is removed from the post.
The industrial relations officer for SINTA, Samson Faisi, says teachers are unhappy with Don Houkura, with claims he has been operating as a dictator.
"The basic thing here is the posting of teachers, which to our dismay as of yesterday, we have noticed that 50 plus teachers are without posts for this year. And he has been doing that over the years and he hasn't followed proper procedures that applied in the teaching services handbook."
Samson Faisi says a petition by teachers calling for the resignation of Don Houkura is now circulating.
