Services are disrupted on many London Underground lines today, after drivers belonging to the RMT walked out in the continuing dispute about a four-day working week.

Today’s 24-hour strike began at 00.01, and a second walkout is planned on Thursday.

Talks aimed at ending the dispute broke down yesterday.

There have been strikes in connection with this dispute already. Although two pairs of walkouts called for 19 and 21 May and for 16 and 18 June were suspended, this week’s walkouts were then announced.

TfL said its proposals are voluntary, and ASLEF has accepted the idea.

After yesterday’s talks at the conciliation service ACAS had failed to reach an agreement, the RMT said: ‘Despite our best efforts in ACAS talks, TfL have failed to provide assurances on our members deeply held concerns around fatigue, reduced flexibility, shift lengths and the impact these proposals could have in a safety-critical role like tube driving.

‘We remain available for meaningful talks, but strike action tomorrow will now go ahead.’

TfL said: ‘It is bitterly disappointing that despite five hours of meetings with the RMT at ACAS and repeated assurances that the four-day working week proposals will remain voluntary, RMT has chosen to continue with its disruptive strike action.

‘We will do all we can to provide as much service as possible.’
