Teachers and doctors say they will join the persistent protests of Kremikovtzi steel mill workers, driven to despair by the economic situation in the country.

The rallies will pile pressure on the Socialist-led ruling coalition in the country, who has recently seen its support among Bulgarians plummet steadily.

Trade unions have called on Economy Minister Petar Dimitrov to resign, citing "his inability to solve the problems of the indebted plant".

Kremikovtzi workers accuse the government of negligence and threatened Thursday more aggressive actions including a national steel mill industry strike and a tent camp in downtown Sofia.
