Workers at one of the country's biggest train companies are to take industrial action during the Olympics in a row over a Games bonus payment.
Up to 1,000 members of the Rail Maritime and Transport union at South West Trains will work to rule, including a ban on overtime, from Friday, the day of the opening ceremony, to August 12, the last day of the Games.
Union members at the firm, which runs services across the South East into London Waterloo, rejected going on strike but voted for other forms of action.
The union has been seeking a bonus for its members for working during the Games, but SWT insisted it had already agreed a wage deal which covers the Olympics period.
Union members working on the London bike hire scheme will strike for 48 hours from Friday morning in a similar row.
Hundreds of RMT members employed by Transport for London will also go on strike over the first weekend of the Games after failing to secure a deal over a bonus.
