Commuters are preparing for travel chaos as tube workers are set to strike for seven days next month.
London Underground workers are to stage a series of strikes next month in a dispute over pay and conditions, the RMT union announced.
The workers will begin the week-long walkout on Friday, September 5.
The union said that rail bosses ‘refused to engage seriously’ with their demands on pay as well as concerns about fatigue management and ‘extreme shift patterns’.
Underground workers were also demanding a reduction in the working week and to honour previous agreements made with staff.
An RMT spokesperson said: ‘Management’s dismissive approach has fuelled widespread anger and distrust among the workforce, who voted in overwhelming numbers to take strike action.’
In a separate dispute over pay and conditions, workers on the Docklands Light Railway will also be striking during this period.
The union said the action would bring ‘significant disruption to the capital’s transport network’.
RMT General Secretary Eddie Dempsey said: ‘Our members are doing a fantastic job to keep our capital moving and work strenuous shift patterns to make sure Londoners get to their destinations around the clock.

RMT General Secretary Eddie Dempsey said workers were not after the ‘King’s ransom’
‘They are not after a King’s ransom, but fatigue and extreme shift rotations are serious issues impacting on our members health and wellbeing- all of which have not been adequately addressed for years by LU management.
‘Coupled with the fact there are outstanding issues around staff travel arrangements, an atmosphere of distrust has been created, where our members feel like no one is listening to them.
‘RMT will continue to engage LU management with a view to seeking a revised offer in order to reach a negotiated settlement.’
A Transport for London spokesperson said: ‘We regularly meet with our trade unions to discuss any concerns that they may have, and we recently met with the RMT to discuss some specific points.
‘We are committed to ensuring our colleagues are treated fairly and, as well as offering a 3.4% pay increase in our ongoing pay discussions, we have made progress on a number of commitments we have made previously.
‘We welcome further engagement with our unions about fatigue and rostering across London Underground, but a reduction in the contractual 35-hour working week is neither practical nor affordable.
‘Given the improvements we have recently put in place in response to concerns raised by our unions, we urge the RMT to put our fair, affordable pay offer to their members and to continue to engage with us rather than threaten strike action, which will only disrupt Londoners.’
