Fresh wave of London Tube strikes begins today in blow to commuters during morning rush-hour

A fresh wave of London Tube strikes will begin today in a huge blow to commuters during the morning rush-hour. 

Members of the Transport Salaried Staffs Association (TSSA) are walking out today and Thursday, wreaking havoc for thousands of travelers in London.

Customer service managers, who are responsible for running the stations, will walk out from 12.01am to 11.59pm on both days in a dispute over pay. 

The union said its members are concerned about potential changes to their terms and conditions, job role and location. 

Transport for London (TfL) has not yet confirmed how the strike will impact services, but some Tube stations could be forced to close at short notice.  

TSSA general secretary Maryam Eslamdoust said: 'Our Customer Service Manager members are united and determined to take strike action this week in defence of their terms and conditions.

'This strike could have been avoided if London Underground had negotiated with us in good faith. 

'Instead, we have been left in a position where London Underground is still unable to explain the impact of its 'Stations Changes' proposals.

'We cannot allow the continued threats to our members' roles, locations, terms and conditions to stand unchallenged, that is why our members are taking strike action this week. 

'We’ll see how quickly London Underground get back round the negotiating table when they see the strength and determination of our members.' 

Last Thursday, planned strikes by Underground drivers who are members of Aslef - which would have impacted services on Monday and on Saturday, May 4 - were called off.

The union said after a series of meetings at the conciliation service Acas, its negotiating team received a proposal that resolved the key issues in the dispute.

Today's strikes come just a day after rail commuters endured yet more disruption after an overtime ban saw trains cancelled across Britain on Tuesday. 

Passengers suffered last-minute timetable changes on the final day of the latest overtime ban by train drivers belonging to the Aslef union at 16 rail operators.

Some feared they would miss flights while others faced being late for work this morning as trains were axed due to crew shortages in different parts of the UK.

National Rail warned to travellers to 'expect significant disruption' throughout today and said services would be 'subject to short-notice delay or cancellation on the day'.

The action affected Avanti West Coast, c2c, Chiltern, CrossCountry, East Midlands Railway, Gatwick Express, Greater Anglia (including Stansted Express), Great Northern, Great Western Railway, London Northwestern, Northern, Southern, South Western Railway, Thameslink, TransPennine Express and West Midlands Railway.

Separately, there were also delays unrelated to the overtime ban - on ScotRail between Glasgow Central and Paisley Canal due to a signalling fault; South Western Railway between Salisbury and Westbury due to a tree blocking the line; Great Western Railway between Liskeard and Looe due to flooding; and on South Western between Brockenhurst and Lymington Pier due to the sea flooding the railway.
