One of the state employees in Simferopol told that the management had already warned employees of a 10% reduction in salaries in May compared to April.

"We have been told there was not enough money in the budget, so they would cut salaries. Previously, we were paid extra for working on holidays, so now they try to avoid engaging us due to austerities," a source said on condition of anonymity.

It is unclear how long these austerity measures will last, according to the source.
