Bad news for all you weekend revellers and night owls. The night Tube, already unfashionably late to the London transport scene, (it was supposed to launch last September), might be instigating another tube strike. Workers in the Rail, Maritime and Transport (RMT) union will be balloting until 24th May over an “inferior” deal regarding their pay and pension conditions. Pray to the transport gods that these issues come to a speedy close, as previous negotiations took 18 months before an agreement was secured.
