Doctors in the Czech Republic have resigned in large numbers as a protest against low salaries and poor working conditions.

The medicos handed in their resignations en masse after the Czech Doctors' Union launched the second phase of a "Thanks, We Are Leaving" campaign, aimed at pressuring the government to increase doctors wages.

The union had been trying to achieve pay levels of around one and a half times the wages already being earned at most health care facilities across the country.

The Czech Republic public health system had 20,000 doctors before the new year.

Since then 3,800 of them have resigned, with Czech Prime Minister Petr Necas's plan for a 10-percent cut in public expenditures coming under intense pressure.

The current gross monthly pay for physicians is around $2,650, including overtime.
