The head of the RMT union has reacted angrily to the announcement that London Underground is hoping to extend the tube's running hours.
General Secretary Bob Crow said:
"It would be nice if senior tube officials had the decency to talk to their staff and their unions within existing agreements before they start spinning ideas out about extending hours and changing procedures.
"Major changes to operational hours mean major changes to rosters and would of course require the recruitment of more staff. They would also impact on maintenance, fleet and engineering works. None of that has been discussed with the unions in any forum and RMT does not conduct its negotiations via the media."
