The Papua New Guinea Public Employees Association says better working conditions for public servants would improve the delivery of government services.
The Post Courier reports the union's president, Anna Igo, was responding to claims from the country's leaders that the public sector is failing to deliver services to the people.
Ms Igo says the government should work with the union to realise the government's development aspirations.
She says critical questions the government needs to ask is why is the public service machinery is not performing to expectations?
Ms Igo says there has been a brain drain from the public service with people lured to the private sector or overseas.
She says to sustain services the government needs to be competitive in the labour market.
Ms Igo says the government should work with the union on issues affecting its employees.
She says issues such as housing, wages, tax, and insurance cover are burning issues for public servants and require immediate government intervention.
