The government says Romania cannot afford the wage increase and contested the law — passed by Parliament — at the Constitutional Court. The court, however, ruled the law was constitutional.
To be enacted, the law must be approved by President Traian Basescu. The government has accused lawmakers in Parliament of passing populist laws to gain public support before general elections on Nov. 30.
Unions say 15,000 teachers protested Wednesday. Teachers were also threatening to go on strike around the country if they do not get the promised salary increase.
The new law means the government will also be under pressure to increase wages for doctors and public servants.
