Union members in Warsaw left Prime Minister Donald Tusk's office on Friday morning after spending two nights in the building, threatening a general strike and saying it was "cowardly" to relocate the office, according to dpa. Members of "August 80" - a more hard-line group than the Solidarity union - have been occupying Tusk's offices since Wednesday in protest over a bill that would slash early retirement. But they left the building on Friday morning after officials said Tusk's office had been temporarily relocated. Tusk was in Frankfurt on Wednesday and in Paris on Thursday for meetings, but offered the unionists a meeting with government officials. He said there were "better ways" to hold talks. The unionists rejected the meeting, and said they wanted to see Tusk directly. 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.
