Student nurses are threatening a Valentine's Day strike in protest at plans to evict them from their homes, which overlook the Millennium Dome.
Unison, their union, called for an inquiry into housing problems that, it said, were hitting student nurses across the country.
The 60 students received notices telling them they must leave their homes by April 1 to make way for a private development of luxury flats.
Unison's deputy general secretary, Dave Prentis, said the students were paid just Pounds 2 an hour and could not afford private rented accommodation.
The University of Greenwich has guaranteed to find accommodation for the nurses.
