Have you got any evidence that the train drivers refuse to modernise or want shorter hours? As I understand it, a lot of the problems are down to crap management who rely on drivers working on their days off rather than employ enough of them.I suspect there is quite a gap between those who work very hard and are productive and those like train drivers that get higher and higher wages but refuse to modernise and in fact demand to work less hours for more money.
But also the answer is rarely working harder or longer hours but being more productive through the use of technology, machinery etc. This requires acceptance of change by the workforce (see trains) and investment by companies. The latter requires an economically competent chancellor to create the right environment for investment.Reeves has done the opposite.
