Lawmakers of the ruling Law and Justice party have pushed through the pay cut after the opposition boycotted the vote. Last year, the party's ex-premier gave her Cabinet ministers bonuses worth an average annual wage.
Poland's parliament on Thursday voted in favor of a 20 percent pay cut for lawmakers following a controversial bonus awarded to government ministers last year.
The draft legislation received 240 votes in favor, most of them cast by lawmakers of the ruling Law and Justice (PiS) party. Opposition parties boycotted the vote, with some of their members shouting "thieves" during the vote.
Last year, PiS came under fire after then-Prime Minister Beata Szydlo gave herself and her Cabinet ministers a bonus ranging from 15,000 euros to 19,000 euros ($17,900 to $22,700) on top of their annual salary.
At the time, Szydlo defended her decision, saying she and her government ministers deserved the bonuses for their "hard work." The bonuses amounted to an average worker's annual salary.
