Sri Lanka has approved a four-day work week for public sector workers to help them cope with a chronic fuel shortage and encourage them to grow food, the government said on Tuesday, as it struggles with its worst financial crisis in decades.

The island nation, which employs about one million people in its public sector, has been hit by a severe foreign exchange shortage, which has left it struggling to pay for critical imports of fuel, food and medicine. Many of the country’s 22 million people have to queue up at petrol stations for hours and have been enduring long power cuts for months.

Sri Lanka’s cabinet late on Monday approved a proposal for public sector workers to be given leave every Friday for the next 3 months, partly because the fuel shortage made commuting difficult and also to encourage them to farm.

“It seems appropriate to grant government officials leave of one working day ... to engage in agricultural activities in their backyards or elsewhere as a solution to the food shortage that is expected,” the government information office said in a statement.
