French Polynesia's primary school teachers have issued a strike notice amid concern that jobs might be cut once the new school year starts.
The union says should there be no agreement by the middle of this week, industrial action will begin on Thursday morning.
A union leader and principal has told Tahiti News that schools are under stress already as some teachers are away because of illness, making it unlikely the schools will be able to manage until the end of the year without getting replacement teachers.
Reports from Paris say 40 jobs are expected to be cut.
A protest march is planned for Wednesday.
