Is it though?
I suspect the majority of the lowest paid, don't actually commute by train to their employment.
Even then, trains are still running and people will have been given the opportunity to make alternative plans.
The idea that this strike action is hitting the lower paid workers more than the shareholders of the rail companies is fanciful.
.
Shareholders will just increase the cost eventually to cover any loses, which again will hit the public.
Shareholders rarely lose out in the long run, however people that need to get to work/hospital appointments etc will be missing out now.
