Claire Mann, TfL’s chief operating officer, said: “We have set out proposals to the RMT for a four-day working week.
“This 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, improving reliability and flexibility at no additional cost.
“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.”
