Warsaw - Some 200 labor union members in Warsaw occupied Prime Minister Donald Tusk's office on Wednesday, demanding a meeting with Tusk on a bill that would slash early retirement.

Members of "August 80" - a more hard-line group than the Solidarity union - said they wouldn't leave until they got a meeting. Tusk was at the time in Frankfurt for talks with the European Central Bank on Poland's entry into the eurozone.

"We know he won't quickly leave his obligations behind," union member Krzysztof Labadz told the Polish Press Agency. "But he has to show up in his parliamentary office sometime."

The union members said they were protesting against proposed cuts in the number of people eligible for early retirement, privitizing hospitals and eliminating the Polish shipyard industry.

The European Commission had demanded for Poland to restructure the Baltic Coast shipyards where Solidarity was launched, or risk losing public aid.

The lower house of parliament approved a bill last week that would reduce the number of people eligible for early retirement from 1.2 million to 250,000. The bill must still be approved by the Senate and President Lech Kaczynski. (dpa)
