The miners have now been on strike for 12 days. The scale of the strike, both its length and the number of strikers, makes it one of the most serious in recent Georgian history.

A video showed miners wearing heavy leather jackets climbing over a compound fence and then pushing in a gate to the GIG office in Tkibuli, central Georgia. Clearly angry and distressed, miners said that they earned $200 a month which, they said, was barely sufficient to survive on.

They want a 40% pay rise and an improvement in the mine’s health and safety record. Media said that 15 miners have died in separate accidents at the mine since 2009.

GIG has said that while it sympathises with some of the workers’ demands, it simply can’t afford to increase their salaries by as much as they want because of falling prices and demand for coal.

“Saknakhshiri GIG as a company of high responsibility will not issue unrealistic promises and will not make populist statements on the immediate increase of the salaries at this stage,” the company said in a statement after meeting the miners.

For the government, the strike piles more pressure on its various economic policies ahead of a parliamentary election later this year. A recession in Russia and a fall in its own currency has hit Georgia’s economy. Growth rates have been reduced, inflation is rising.

And the Tkibuli miners are not the only group of workers striking in Georgia. Media reported that workers at a glass factor in Ksani have also gone on strike.

Other companies, especially in the mining sector, have been laying off workers.
