Talks to try and avert next week’s planned tube strikes have collapsed.

Talks to try and avert next week’s planned tube strikes have collapsed.

Officials from rail unions and Transport for London walked out of talks after just three hours.

The Rail Maritime and Transport union said around 200 maintenance workers employed by Alstom-Metro at depots on the Jubilee and Northern lines will stage four 24-hour walkouts from the evening of September 5 in a row over pay and conditions.

The strikes will start at 7pm on September 5, with further action scheduled for the same time on October 2, November 1, and November 27.

An indefinite overtime ban will also begin on September 5 after a vote in favour of action by union members. The action will take place a day before strikes by up to 10,000 members of the RMT and the Transport Salaried Staffs Association (TSSA), who will walk out for 24 hours from 5pm on September 6.

The action will include an indefinite overtime ban from September 6, following votes in favour of strikes over plans to cut 800 jobs among station staff.

RMT general secretary Bob Crow said of the latest dispute: “Alstom is a major trans-national company that has been making immense profits and is happy to shovel dividends to its shareholders, but has offered what would amount to a pay cut to our members.
