Conductors on Southern railway have voted to go on strike in a dispute over changes to their role and driver-only trains, the RMT union has announced.
Of the votes cast 306 were in favour of walkouts and 14 were against. A total of 320 to one backed other forms of industrial action.
The union is against the introduction of a new grade of on-board supervisor and plans for drivers to operate doors.
Operator Govia Thameslink said the changes would make staff more visible.
The RMT said it was fighting to keep the conductor grade and the changes were “nothing short of bullying and harassment”.
Southern operates in Sussex, Surrey and parts of Kent and Hampshire.
