That’s a very strong possibility, Eddie.
Fifty years ago the end of steam was imminent on BR. At that time steam locomotives required two people (a driver and a fireman) to operate them. When diesel and electric locomotives took over the unions insisted that two men were still to be employed to operate them when only one was necessary. Only one person was needed to operate the train but the unions insisted that two were employed in each cab “for safety reasons” (even though adequate safety mechanisms were in place in the event of the driver becoming ill, or whatever). Now nobody is surprised to see an “Inter-City 125” with just one person in the cab.
Where “driverless” trains are operated in the UK (e.g. the Docklands Light Railway and parts of the London Underground) there is still a member of crew on board to operate various aspects of the train and to provide a safety backup. The only true “crewless” trains I can think of are the very short services in places like the Gatwick inter-terminal shuttles. These are very short in length and swift access to the trains is available throughout the route.
Of course these things will change and the Unions must change with them. But this is not about that. The Unions have made it quite clear that this action is designed to jeopardise the elected government and, if possible (though highly improbably) bring it down. The Unions have not, alas, learned, despite having their noses blooded on many occasions, that this is not the way things are done in the UK. Meanwhile the Unions “regret” that their action is necessary and their employers’ customers suffer whilst they pursue their idealistic nonsense.
