Samsung's largest labor union is beginning its three-day strike in South Korea. The union is now 36,570 members strong, making up a quarter of Samsung Electronics' workforce.
It is demanding one more day of annual leave, a change to the company's draconic bonus structure, and better pay overall.

The union has 6,540 members participating in the strike, and the union says 5,211 of these are workers involved in semiconductor manufacturing.

This week's three-day strike is not estimated to seriously impact Samsung's productivity, but the union has pledged to begin a second five-day strike next Monday if demands are not met in time.
