Thousands of people took to the streets of Lisbon and other Portuguese cities on Saturday to condemn fresh belt-tightening measures.
The global economic institutions are keeping an eye on Portugal's implementation of spending cuts and reforms required in return for the 78-billion-euro ($102 billion) rescue package the country received in 2011.
The reductions and reforms caused the Iberian government’s economy to shrink by 1.2 percent in the second quarter, which marked a sharp increase compared to the 0.1-percent rate at the start of the year.
Dockers have brought most of Portugal’s ports to a standstill in an attempt to make the government in Lisbon reverse a new labour code meant to relax employment regulations.
Leaders of the dock workers' union Oficiaismar said on Monday that the ports of Lisbon, Setubal, Sines and Aveiro on the Portuguese mainland were hit as a result of the walkout over working conditions and job cuts, AFP reported.
Oficiaismar official Carlos Coutinho stated that cruise lines had to change their schedules because of the strike.
Meanwhile, a three-day walkout at two main oil refineries has drastically reduced production.
There are reports that 90 percent of the staff at Sines, situated 150 kilometres (95 miles) south of the capital Lisbon, and Matosinhos, situated 272 kilometers (169 miles) northeast of Lisbon, walked out on the first day of the strike.
