Main opposition New Democracy (ND) leader Antonis Samaras on Friday visited the Elefsis Shipyards, which are facing viability problems.
Samaras was briefed by the management and workers on the effort being made to maintain the jobs at the shipyard, and called on the government to head to a course of growth, expressing confidence in the country's labor potential.
The ND leader said that the unemployment rate in Greece has "hit red", affecting every household.
Greece, he added, needs to enter a developmental track, stressing that this was possible with the country's workforce.
The revenues of the shipyard, which employs more than 800 people, has plunged to 17 million euros this year from 37 million in 2008.
