"We must say this out loud: today public sector employees in the fields of culture, and arts, but also nurses, medical workers, office workers, and social workers are in an exceptionally difficult situation," Tusk said.
He also added that public sector employees should be entitled to a 20 percent pay hike, as the country faces an inflation "as high as 11 percent."
According to Tusk increasing wages in the public sector could cost the state budget up to PLN 30 billion (EUR 6.47 billion).
The reading was 0.8 percentage points higher than forecast by economists polled by Poland’s PAP news agency.
In February, the prices of consumer goods and services in Poland were 8.5 percent higher than in the same month a year earlier, according to the Central Statistical Office.
In January, Poland's consumer price index stood at 9.4 percent, the statistics agency has said.
The Polish central bank’s Monetary Policy Council last month raised key interest rates for the sixth consecutive time in a bid to tame inflation.
