The RMT union is promising 'all-out industrial action' if an idea to make tube trains driverless is considered.
The Conservatives on the London Assembly have suggested replacing drivers with automatic trains, which it's claimed would save 141 million pounds.
The union claims the proposal is 'lethal and ill-conceived'.
