Unions representing high school teachers in Greece have voted to hold "long-term" strikes starting on Monday against public sector staff cuts ordered by the government as part of its bailout agreements.

The move represents the first major challenge to the government over its plan to suspend 25,000 employees this year and sack 15,000 others by the end of 2014.
