Coal miners at ArcelorMittal's Kazakh unit and the biggest steel mill in the country, ArcelorMittal Temirtau, have ended their sit-in strike and emerged from the mines, the company said Dec. 15, Reuters reported.

Hundreds of workers started the sit-in on Dec. 11, as the miners demanded a pay increase of 100%, a reduction of the pension age to 50, and a number of other conditions.

The strike ended after ArcelorMittal offered a pay increase for employees working underground by 30% and threatened to pursue legal action against the workers.

The company will continue negotiations with the miners.
