In this May 23, 2012 file photo released by British Airports Authority, over 2,400 pieces of baggage are seen lined-up in Terminal 5 at Heathrow Airport during a baggage handling exercise to prepare staff at London's main airport for the forthcoming Olympic and Paralympic games, in London. Officials at Heathrow are well aware that losing or breaking the bags of high-profile athletes could be a public relations disaster - and have geared up to ensure that doesn't happen. Heathrow has recruited 1,000 Olympic volunteers clad in bright pink to help and created special teams to deal with oversize items like javelins and bikes.
Members of the Public and Commercial Services Union have voted for the 24-hour strike in a dispute over pay and job losses.
The strike, announced Thursday, is a headache for the British government, which is eager to avoid any disruption as visitors descend for the July 27-Aug. 12 games.
Heathrow Airport has been beset for months by long lines at passport control that the union blames on government spending cuts.
