Lesotho's clothing and textile industry could be crippled by a national strike unless the government agrees to minimum wage increases, union leaders have warned.

Workers will disrupt production by staging sit-in protests at factories and picketing the plants unless the government aggress to union demands for a "living" wage, officials from the Lesotho Clothing and Allied Workers Union (LECAWU) said.

LECAWU secretary general, Daniel Maraisane, told the country's press that doors for negotiations seem to have been shut as the government is adamant on a 6.5 per cent minimum wage increase.

"We are still prepared for talks, but the sooner the better as by Friday we will be putting all plans to go ahead," he said, before adding that the strike could last anything from one day to one week or even longer.

Clothing and textile industry workers are demanding a taxable living wage, which would be around M880, while the government has set the minimum wage at M552.

The chairpman of the Lesotho Exporters Association, Jeniffer Chen, said she was against such a strike and called for workers not to disrupt production if industrial action goes ahead.
