Nearly 1200 workers from the Sao Vang shoe factory in Haiphong City, Vietnam's northern city, went on strike in May 20th.

The workers said that the company did not meet their demands for higher wages, and inflation led to higher costs.

Vietnam experienced a wave of strikes this year. In April, Vietnam's consumer prices rose by 21% over the same period last year.

The workers suspended their wages on Monday and asked the management to raise their wages.

However, most of these strikers return to work in second days.

At present, Vietnam's per capita wage is 50 dollars (800 thousand Vietnamese shield), and management plans to raise wages to 75 dollars, but workers are demanding higher wages.

In addition, Vietnam's monthly salary has been 38% higher than the monthly minimum wage of Vietnamese workers owned by the government.

Sao Vang specializes in shoe manufacturing. Most of its products are exported to Europe and Asia.
