The National Assembly Standing Committee stated that salaries should reflect the quality of the work done and be dictated by market forces.
Law makers also suggested the number of public holidays should be increased.
However, Truong Thi Mai, chairwoman of the NA Committee for Social Affairs, argued that a minimum wage should be applied to regions that had a high ratio of low-skilled workers.
"We should only set a minimum wage for sectors and industries that employ low-paid workers. This would prevent employers from taking advantage of their employees," she said.
According to the Viet Nam General Confederation of Labour, current wage levels only met 60 per cent to 70 per cent of a worker's living standard.
Meanwhile, a report by the NA Standing Committee stated that the minimum wage was only applicable to 10-20 per cent of employees working in the most vulnerable industries.
Nguyen Kim Khoa, chairman of the NA Committee for National Defence and Security, said the minimum wage did not protect vulnerable employees.
"Many foreign enterprises are taking advantage of the law to pay their employees the least amount to boost profits," he said.
The current Labour Code sets four different minimum wages for different regions and different industrial sectors.
Yoon Youngmo, from the International Labour Organisation in Ha Noi, said it was a mistake to set more than one minimum wage level. "It is far more difficult and complicated. How do you clearly define different industrial sectors. How do you determine what minumum wage should be for that sector?" he said.
He also said the Government should not be responsible for determining an employees' wage level.
"This situation reflects the weakness of wage negotiations between trade unions and employers," he said.
He said trade unions should take a bigger role in wage negotiations. "That way the minimum wage would protect vulnerable workers."
The NA Standing Committee has suggested there should be 10 national holidays a year, one more than the current level. They suggested the extra day should be added to the four-day Tet (Lunar New Year) holiday.
"Facts have shown that workers are unproductive on the first day back from Tet. It would be far better to give workers a full week off," said NA Chairman Nguyen Sinh Hung.
NA vice chairwoman Nguyen Thi Kim Ngan, former Minister of Labour, Invalids and Social Affairs, agreed that workers should have more public holidays. She said Vietnamese workers had fewer public holidays than other workers in the region.
The current Vietnamese national holidays are New Year's Day, Hung Kings' day (March 10 on the Lunar Calendar), April 30 (Reunification Day), May 1 (May Day), September 2 (National Day) and the four Tet holidays.
In comparison, S.Korea and Singapore have 14 public holidays, Malaysia has 17, the Philippines has 20 and China has 21. Meanwhile, there are 10 national holidays in the UK, 11 in Sweden, 12 in the US and Canada and 13 in Nigeria.
Pham Thi Hai Chuyen, Minister of Labour, Invalids and Social Affairs, said her ministry would add the extra holiday suggestion to the draft amended Labour Code.
In addition to public holidays, Vietnamese workers have 12 paid holidays each year.
Meanwhile, some lawmakers have suggested the number of working hours in the month be increased to 360 from the current 200.
NA Economics Committee chairman Nguyen Van Giau said workers would welcome the extra overtime.
Phung Quoc Hien, chairman of the NA Committee for Finance and Budget, suggested the increased hours should only be applied to specific industries and for workers of a certain age, for health reasons.
Meanwhile, the ILO's Youngmo said it was important to ensure workers were not forced into doing unwanted overtime.
"It is important that workers are able to choose whether to accept overtime work or not," he said.
Viet Nam's Labour Code came into effect in 1995 and has been amended three times. — VNS
