Brace yourselves, London, because yet another tube strike could be heading our way and there's no prizes for guessing what the dispute is over this time. Yep, the non-existent Night Tube is rearing its ugly head again, as engineering and maintenance workers in the RMT union are voting on whether to strike over their pay and conditions for the new 24-hour weekend service.
The RMT agreed a deal for its drivers two months ago, but said that workers employed by Tube Lines (which is owned by London Underground) were offered an 'inferior' deal. The ballot for strike action opens today and closes on May 24.
