DLR staff to vote over strike action
Workers on the Docklands Light Railway are threatening to walk out following a row over pay and working conditions.
The Rail, Maritime and Transport union is also accusing management of hiring contract staff to undermine jobs and of a failure to provide adequate training.
The ballot for strike and action short of a strike will run between December 30 and January 16.
RMT General Secretary Bob Crow said: "It is solely down to the actions of the Serco DLR management that RMT has had no option but to move to a ballot of our members across Dockland's Light Railway to try and force the issues at the heart of this dispute to be both addressed and resolved.
"RMT will not tolerate the cavalier abuse of procedures, agreements and pay negotiations which has led to the complete breakdown of industrial relations on this vital section of the London transport operation."
Mr Crow said the Transport for London and management company Serco had allowed a "catalogue of complaints to build up".
Docklands management said it is looking into the union's allegations.
Kevin Thomas, managing director of Serco Docklands, said: "We continue to meet with the union to agree a pay deal for 2014 and we are actively investigating the other issues they have recently raised.
"This action is unnecessary and we are working to ensure we continue to deliver a normal and reliable service to DLR passengers every day."
