In his words, some businesses might not withstand the MMW raise and might move into the shadow.

Edita Maslauskaite, acting president of the Lithuanian Free Market Institute also warns the MMW increase is likely to raise the prices of goods and services, hitting the most socially vulnerable groups.

"Such a drastic increase does not meet economic tendencies. It can hit small and medium enterprises, in other words, regions, as regions already now have difficulties coping with the MMW," Sartatavicius told BNS Lithuania.

The MMW was raised 7.5 percent to 555 euros as of the start of this year, after going up annually for the past few years.

Moreover, wage rises in Lithuania are way ahead of growth in labor productivity, and Lithuania risks losing its competitiveness, the representative of the industrialists said.

"We need to focus on raising labor productivity, not the MMW. To improve productivity, we need certain investment. So businesses need help here," Maslauskaite said.

The MMW increase is likely to mostly affect sectors relying on unqualified workers, for example, construction and catering businesses.

Maslauskaite also called the decision to raise the MMW to 670 euros "cynical".

"Cynical. That's the only way you can call the decision to raise the MMW to 607 euro before tax," she said, adding that the move would not improve the financial situation for the lowest-earners, pensioners and those unemployed.

"And the possible increase in prices, caused by the rising MMW, will hit these groups the hardest," the institute's acting president said.

Around 156,000 people in Lithuania including around 28,000 employees of budgetary institutions, earn the minimum monthly wage or less.
