Labor unrest is expected to spread following massive layoffs at several IT giants, with experts calling on multinationals to take the issue seriously.

Cisco Systems has announced a plan for global job cuts, while thousands of Microsoft employees in China are trying to negotiate a deal for better compensation following layoffs.

“Labor disputes involving overseas information technology companies are set to grow for the next two years at least as the Chinese economy slows,” Zhang Zhiru, a labor rights expert at Shenzhen Chunfeng Labor Disputes Services Center, said on Thursday.

He said that although most of the IT companies are willing to provide compensation higher than that provided for under Chinese law, this does not mean they have done a perfect job.

“The law only sets a minimum level. Companies with better financial power should definitely pay more (in layoff compensation) if employees need this,” Zhang said.

Cisco, the world’s largest telecom equipment maker, plans to cut up to 6,000 employees globally. It did not say how many employees will lose their jobs in China, one of the world’s biggest IT consumers.

Microsoft’s biggest cut in the company’s history could cost at least 4,000 jobs in China, according to a person familiar with the issue. Most of the cuts will come at three Nokia facilities the company acquired months ago.

More than 500 employees at a Microsoft handset development site in Beijing handed in a signed request last week calling for direct talks with management of the company.
