Greece's two main labor unions have announced a general strike against planned austerity measures on September 26.

A spokeswoman for the General Confederation of Greek Labor said the action would involve members of both the country's largest private sector union and its largest public sector union.

The 24-hour strike is meant to speak out against some $14.8 billion in budget cuts demanded by Greece's creditors: the European Union, International Monetary Fund and the European Central Bank.

Greek doctors, teachers, and municipal staff held strikes this week to protest the new measures, which include cuts to pensions, salaries, and health care.
