Docklands Light Railway workers are to stage a 48-hour strike in a dispute over pay and conditions.

Security staff and cleaners employed by facilities company Interserve will walk out from 5:30am tomorrow (May 27).

Members of the Rail, Maritime and Transport (RMT) union voted 4-1 in favour of action.

RMT general secretary Mick Cash said: "The union will not sit back while core issues on pay and working conditions are left unresolved.

"The ballot result delivered a huge democratic mandate that shows the anger amongst our members and it is about time that Interserve woke up and took note.

"Our members will be sending that message loud and clear over the next two days in a dispute which has ramifications for the entire outsourcing industry in the UK and its virulent anti-union stance."
