Guards on London Overground have voted for strike action in a row over jobs. Members of the Rail Maritime and Transport union backed walkouts by 9-1 as part of a campaign against cuts.
The union said 130 guards' jobs face being axed under plans to introduce driver-only operations on the network.
General secretary Bob Crow said:
"RMT have sent out a clear message in this ballot for both strike action and action short of a strike on London Overground over the appalling, cash-driven assault on our guards members and the absolutely essential role that they play.
"These are the very same staff who have been praised for safely evacuating passengers from emergency situations and who are the eyes and ears of the service at a time of growing violence and thefts on our trains."
