UK worker strikes may disrupt the Olympics

LONDON — Athletes and sports fans attending the 2012 Olympic Games may face disrupted journeys after UK immigration and rail workers announced separate strikes.

British Border Agency staff and other Home Office employees will walk out on July 26, the day before the opening ceremony, in a dispute over jobs, pay, and the privatization of services, the Public and Commercial Services Union said Thursday.

ASLEF, the rail union, said separately that drivers will strike for three days at Stagecoach Group’s East Midlands Trains, which connects London with Loughborough, location of the main preparation camp for British athletes competing in the Games.

‘‘This strike threatens Team GB’s ability to plan travel from their UK base in Loughborough and would disrupt journeys for thousands of commuters and spectators,’’ Transport Secretary Justine Greening said. ‘‘If there were an Olympic sport of self-interest, ASLEF union leaders would win it.’’

Train drivers will walk out Aug. 6 — when the men’s 400 meters final will be held — and the following two days.

In addition to their one-day strike, immigration officials will refuse overtime and work strictly to contract between July 27 and Aug. 20, PCS General Secretary Mark Serwotka said in a statement, adding that the government has acted ‘‘recklessly’’ in cutting jobs and ‘‘provocatively’’ in refusing talks.

On Thursday, Home Secretary Theresa May said that the Border Agency strike call was ‘‘shameful,” while John Cridland, director general of the Confederation of British Industry, said the timing of the walkout ‘‘beggars belief.’’

London’s Heathrow airport, through which the bulk of overseas competitors are arriving for the Games, will aim to maintain a smooth and secure service owner BAA Ltd. said.
