Greeks demanded their government protect wages, pensions and restore collective bargaining on Monday, staging a noisy reminder of popular dissent to leaders poised to start fresh negotiations with lenders. Athens and its creditors are due to launch a fresh round of talks this week on reforming its labour market, among conditions of a multi-billion euro bailout and a vital economic test if the indebted country is ever to win debt relief. "A leftist government should speak in the name of the people, not in the name of capital." Leftist Prime Minister Alexis Tsipras was re-elected a year ago on a pledge to revive collective bargaining and resist reforms that may lower the minimum wage.
