London Underground train drivers are set to strike for three days over a long-running dispute about pay and plans for an all-night tube service.

Leaders of the Aslef union will meet on Monday to decide whether to go ahead with strikes that would cripple tube services in the capital. If the union’s executive agrees, there will be a 24-hour strike from 9.14pm on 27 January, followed by further 24-hour strikes from the same time on 15 February and 17 February.

London Underground has offered a four-year pay deal and said it will hire part-time drivers to staff an all-night service at weekends. But unions have been seeking assurances for months about terms and conditions for their members.

Finn Brennan of Aslef said: “We genuinely regret the inconvenience that will be caused by any action, but the behaviour of London Underground’s senior management team has left us with no other choice.

“Our negotiating team last met London Underground at Acas [the conciliation service] on 10 November and since then they have refused to talk to us despite repeated requests.

“Our members have been extremely patient; they have waited for more than three and half years for promised talks on improving work-life balance. There is still no indication when they will receive the pay rise that was due last April.”

We will not accept a zero-hours culture being introduced and working conditions undermined Finn Brennan, Aslef

Brennan added: “We want to see an all-night service introduced and we are not opposed to the recruitment of part-time staff. But we will not accept a zero-hours culture being introduced and working conditions undermined. Aslef wants a fair deal for existing staff and for new employees.

“We are ready to talk at any time to finally resolve this dispute. It is time for the mayor of London and his team at Transport for London to stop the political posturing and engage with us to stop London suffering more disruption.”

A spokesman for the Rail, Maritime and Transport union said: “RMT’s executive will be taking a report from our London regional organiser on the total breakdown of negotiations over the linked issues of night tube and pay at a meeting on Monday.

“That report will include a number of recommendations for action in support of our members in this dispute with London Underground.

“Any decisions on action are a matter for the union’s executive as set out under RMT’s rule book.”

The RMT is also in dispute over station staffing issues and is balloting 1,300 tube line maintenance staff over pay and the night tube.
