LONDON (AP) -- Union leaders for the London subway system say they'll be turning up the pressure for a deal to compensate workers for extra duties during the Olympics.
Bob Crow, the general secretary of the Rail Maritime and Transport Union, said in a statement Wednesday an offer from the London Underground is insulting and doesn't compensate workers for demand expected during the July 27-Aug. 12 event.
Underground officials disputed Crow's assessment, but said the matter is still under negotiations. They say subway staff will be asked to work flexibly and that they intend to acknowledge their contributions.
Transportation is a key concern for authorities, who have invested billions in upgrading transport links.
The success or failure of the Olympics hangs in part on the aging system managing an increase in demand.
