About 5000 garment factory workers marched from their factory to Phnom Penh city hall on Thursday (September 5) demanding a raise and bonus payments.
Workers from the SL 1 and SL 2 garment factories, mostly women, for about six kilometers to the city hall where they blocked the road.
The workers currently get minimum wage of $80 per month but they are demanding a rise to $150 per month.
The workers also calling on the government to sack the manager whom they accuse of standing in the way of a resolution.
The garment industry is Cambodia's third-biggest currency earner behind agriculture and tourism.
The sector shed almost 30,000 jobs in 2009 after a drop in sales to the United States and Europe.
Reports showed the country exported garments, textiles and shoes to the value of $2.3 billion last year, down from $2.9 billion in 2008. More than half goes to the United States.
