Members of the Rail, Maritime and Transport union will walk out for between 24 hours and four days following a previous stoppage last month which disrupted travel in the capital.
The union is in dispute with operators Keolis Amey over claims of bullying, breaches of agreements and "abuses" of the use of agency staff.
RMT general secretary Mick Cash said: "RMT members on Keolis Amey Docklands have already shown their anger and determination with rock solid strike action but they are still not being listened to and that leaves us with no option but to schedule blocks of industrial action early next year.
"Our members on DLR are furious at the way that Keolis Amey are trying to bulldoze through some of the worst working practices and conditions that we associate with the operations of the most cheapskate and anti-union companies in the transport sector.
"We will not sit back and allow this aggressive and bullying culture to develop on this key part of London's transport network."
The first strike will start at 3.59am on January 11 for 24 hours followed by more walkouts at the same time on January 13, February 8 and 11 and March 7, 10, 21 and 29. The final two strikes will last for four days.
Kevin Thomas, managing director of KeolisAmey Docklands, said: "We have held a number of meetings with RMT representatives in recent weeks, where considerable progress has been made.
"These meetings are currently ongoing and it is extremely frustrating that RMT have decided to announce further dates for strike action rather than proceeding to seek resolution to the issues.
"Such action will cause unnecessary disruption for our passengers, which I believe is avoidable.
"As always, we continue to seek meaningful and reasonable discussion with the union, with a view to achieving resolution and preventing disruption for our passengers."
