The RMT has rejected a suggestion for Tube drivers to voluntarily work a four-day week.
Under the proposals, most drivers would see their working week lowered from 36 hours to 35 hours, however their wage would stay the identical.
The union mentioned it was involved about shift lengths, unacceptable working time preparations and the doable affect of fatigue on security.
The union it wished a 32-hour week over 4 days, which might see drivers work three fewer hours every week for a similar wage.
RMT official Jared Wood mentioned: “TfL need to come forward with changes to their proposals for this dispute to be resolved.”
Claire Mann, TfL’s chief working officer, mentioned the 4 day week proposal “allows us to offer train operators an additional day off, whilst at the same time bringing London Underground in line with the working patterns of other train operating companies.”
She added: “The changes would be voluntary, there would be no reduction in contractual hours and those who wish to continue a five-day working week pattern would be able to do so.”
