Eurozone finance ministers have postponed their decision on a 12bn-euro ($17bn; £10bn) loan to Greece until it introduces further austerity measures.
The ministers said they expected to pay the latest tranche of a much larger aid package by mid-July.
But its release depends on the Greek government surviving a vote of confidence on Tuesday.
Parliament then must also pass 28bn euros worth of new spending cuts and economic reforms.
This latest tranche - of a 110bn-euro European Union and International Monetary Fund aid package - is crucial as Greece needs the aid by July to pay off the creditors of its huge debts.
But there are also practical questions about whether the country can implement the reforms being demanded in return.
Greeks have already seen wages and pensions cut and there have been regular, mass demonstrations - even riots - in protest.
The latest public opposition to the cutbacks involves Greek workers at the state-owned electricity company, who are on the first day of a 48-hour strike.
German Giant Says US Workers Lack Skills
A mismatch in the US labour market between the skills of unemployed people and the jobs available is making it hard for some companies to find the right staff despite an unemployment rate of more than 9 percent, one of the country’s largest manufacturing employers has warned.
Eric Spiegel, chief executive in the US forSiemens [SI 134.51 3.43 (+2.62%) ], the German engineering group, said the problemexposed weaknesses in education and training in the US. Siemens had been forced to use more than 30 recruiters and hire staff from other companies to find the workers it needed for its expansion plans, even amid an unemployment rate of 9.1 percent
“There’s a mismatch between the jobs that are available, at least in our portfolio, and the people that we see out there,” Mr Spiegel told the Financial Times. “There is a shortage (of workers with the right skills.)”
He said Siemens was having to invest in education and training to meet its staffing needs, including apprenticeship programmes of the kind it uses in Germany. (Slideshow: What workers get, country by country).
