Strike negotiations could be used to prevent rail workers action
Southeastern train employees will hold a ballot to decide whether they strike over job cuts.
Managers at Southeastern trains may be required to enter strike negotiations following the news that employees are to take a ballot regarding industrial action.
Members of staff who work at Charing Cross and Victoria stations are voting on whether to stage the walkouts in a protest over plans to cut the position of team leader.
Rail Maritime Transport union general secretary Bob Crow said: "Just days after their services collapsed into total chaos in the cold snap, Southeastern have been caught out yet again cutting staffing and operational costs to maximise profits."
He added that the company's proposed move will compromise passenger safety and cause chaos on the platforms at Charing Cross and Victoria.
Mr Crow noted that people are at risk of being made redundant, while the operator has increased fares by 13 per cent.
Earlier this week, the Independent reported that National Grid faces the prospect of a quarter of its 10,500 staff staging industrial action in January over a row concerning pay.
