Hundreds of thousands of Portuguese workers took part in a general strike on Thursday of last week.
Garbage collection services were the first to stop.
Hundreds of schools were closed and health workers also struck in large numbers.
Vice-president of the tax workers trade unions, Marcelo Castro, said that more than 80 percent of the sector participated in the strike.
“This is a historic strike. We have never had such a big participation,” he said.
Bettencourt Picanço, from the state technicians union, said that people “expect the government to stop its systematic attacks on public sector workers”.
According to Ana Avoila, the coordinator of the Joint Front of Public Administration Trade Unions, workers are planning further action.
“We will promote large impact events and demonstrations in April and May because we believe that workers must keep on fighting to avoid losing the few benefits that they still have.”
