ATHENS — Greece’s Parliament late Sunday approved a contentious plan to dismiss 15,000 civil servants by the end of next year as part of a new package of economic measures that the country must enforce to clinch crucial financing from foreign creditors.

Euro zone officials meeting in Brussels on Monday are expected to approve the release of about 2.8 billion euros, or about $3.65 billion, in loans. The money had been due in March but was delayed after negotiations between Greece and the so-called troika of its foreign lenders stalled over the lenders’ demands for civil service cuts.

The troika, which comprises the European Commission, the European Central Bank and the International Monetary Fund, has been meting out aid in exchange for belt-tightening measures. They are to decide on another six-billion-euro installment in May, assuming Greece adopts further reforms, including an overhaul of a tax collection system.

The latest measures passed into law in a vote held shortly before midnight on Sunday with 168 votes in the 300-seat House.
