The polls also suggest that most people believe, as I do, that firefighters should be paid at least £30,000 a year - not the £21,000 they currently receive. If the Fire Brigades Union does strike, there will be serious concerns about the safety of the Tube network - and as a transport union, safety is always our first concern. If London Underground and the other underground railway operators in Britain had any sense, they would close down their systems on days that proper fire cover is not available.
