STORY: Samsung's labor union said Friday it's still committed to a planned strike starting next week.

That's despite the company proposing to resume pay talks without conditions.

Government-mediated negotiations between the union and the company over pay and bonus schemes collapsed this week.

It led to more concerns about a strike at the world's biggest memory chipmaker.

The union said Friday it was willing to hold new talks after June 7.

But it kept plans for an 18-day strike from May 21 which could disrupt production at the chipmaker.

The union is angry over what it calls a massive gap in bonus pay with rival chipmaker SK Hynix.

They've warned that more than 50,000 workers could walk off the job next week.

Samsung executives urged the union to resume talks.

They also apologized to the public and the government for the disruption caused by the labor fallout.

They've vowed to approach negotiations with an open attitude and keep up efforts to reach an agreement.

The company said executives were heading to the company's Pyeongtaek campus to meet the union leader.

South Korean government officials have said a strike at Samsung should be avoided at all costs.

They worry about the risk it poses to economic growth, exports and financial markets.

Investors didn't like what they heard and shares were down close to 10% after the update.

Analysts blamed the share drop on growing uncertainty over the potential impact of a strike on production.

They also fear whether Samsung can meet its commitments to customers due to potential industrial action.
