Portugal's unions hope to bring the country to a near standstill on Wednesday as they stage a general strike in protest at planned wage cuts.

葡萄牙工会希望在星期三举行一场大罢工使国家处于停滞状态，此次罢工旨在抗议工资削减计划。

Transport, industry and schools are set to be severely¹ affected² by the strike, the unions said.

The strike comes two days before the parliament in Lisbon is to vote on an austerity budget（紧缩财政） .

The budget aims to quell³（平息，镇压） international ease over Portugal's public spending and deficit⁴（赤字） .

For the first time in 20 years, the country's main unions UGT and CGTP have united in a call for a national day of industrial action.

They expect workers from the private and public sector⁵ to take part in the strike, the head of the CGTP, Manuel Carvalho da Silva, said.

"The mobilisation of workers is enormous," he added.

The strike will hit banks, media and petrol supplies, the unions say.

They also aim to paralyse the country's ports, and hundreds of flights are set to be cancelled.

Many Portuguese⁶ have been angered by the government's plans to cut wages for public sector workers, freeze pensions and increase taxes.

Bond commitments

However, analysts⁷ say the walkout is unlikely to stop the passage of the austerity budget, given that the opposition⁸ Social Democratic Party (PSD) has said that in order to not jeopardise（危及） the country's fragile finances it will abstain⁹ from（放弃，戒绝） the vote on Friday rather than vote against the measures.

The PSD position is crucial as Lisbon is trying to convince international investors¹⁰ that Portugal will not be forced to seek a bail-out like Ireland or Greece.

The austerity budget aims to reduce Portugal's deficit from 7.3% to 4.6% of GDP in 2011 through a combination of spending cuts and tax raises.

BBC Europe business correspondent Nigel Cassidy says that Portugal has failed to prosper¹¹ or drive up productivity since joining the euro at what many now say was an unrealistic exchange rate.

The country found it especially difficult to compete with China in a previously¹² strong sector, the manufacturing of textiles and shoes, our correspondent adds.

With 80% of its public debt held abroad, the country now finds itself at the mercy of bond traders and wants to convince the markets that it will be able to meet its commitments, our correspondent says.
