As a passenger with an interest in rail, and a public sector / military background I rarely comment here. I do recognise that in the main many parts of the rail sector have lots of genuine grounds for strike action and concerns about safety and pay. I also recognise that there is a lot of misreporting too that doesn't help.
But, with all that said, this is a ditch that is simply not worth dying on. Technology changes, tablets are widespread now and I'd be comfortable assuming that the vast (95% plus) majority of those impacted own a smart phone or tablet and use it daily for personal reasons. Going on strike for extra money to access a tablet and inconveniencing hundreds of thousands of people who do this sort of change regularly does not help make the case for the rail sector. If you want public support for the fights that matter, don't pick fights for the sake of it that burn away at public goodwill.
