Thousands of Greek workers demonstrated against pension reforms. The strike was the sixth this year, shutting down public services. The government says that the changes to the pension system are necessary for the Greek economy, and that this will be good in the long term. Greek unions said that they will continue to fight against the pension reforms, which they say are unfairly punishing those who did not cause the problems.
