A team of foreign lenders arrived in Athens on Wednesday to monitor efforts by the Greek government to introduce additional budget cuts worth 11.5 billion euros (14.3 billion dollars) so that it can receive the next tranche of emergency aid.

According to a report by the so-called troika - comprising the European Commission, the European Central Bank (ECB) and the International Monetary Fund (IMF) - leaked to the Greek press ahead of talks due to begin on Friday, the government must introduce drastic labour market reforms, including a six-day working week.

Greek Prime Minister Antonis Samaras is looking to secure additional time to implement the required austerity measures, but the troika insists it must deliver on their demands.

Samaras is scheduled to meet with troika officials on September 10.

After their visit, the lenders will decide whether to grant Greece the next bailout payment, worth 31.5 billion euros. Without that money, Greece would be forced to default on its debt.

In order to jump-start the economy, the leaked report proposes further cuts to the minimum monthly wage, currently at 586 euros (736 dollars), as well as to private sector salaries.

Controversially, it also suggests increasing the number of workdays, from five to six per week, across all sectors.

The government has issued few details on the new austerity package, which is expected to focus largely on further pension and public sector pay cuts.

The latest cuts are expected to trigger a new wave of protests.

Dozens of hospital doctors marched towards the country's Finance Ministry on Wednesday to protest government plans to once again slash salaries. Protesters also want to be paid money owed for overtime and emergency shifts.

Similar protests are expected to be held by the police, firefighters, coast guards and university professors.
