Lithuanian teachers intend to strike demanding higher wages.
Some schools may be closed on Monday.
"This will be the largest protest, with up to 600 educational institutions ready to join and which may last for several weeks," broadcaster LRT said in the release.
According to the chairman of the trade union of educators of the Republic, Andrios Navikas, the exact number of teachers who joined the action will be known on the morning of November 16. The union insists on increasing the salary ratio of the teaching staff by 10%.
