Anything that affects customer confidence that a good or service will be available is likely to have a detrimental affect on a business - alternatives will be sought and utilised - it's one of the nuances that the RMT▸ /ASLEF» overlook in their endless quest to live in 1975.
Most of the rest of the World has moved on so far when it comes to industrial relations and looks on the railways with a mixture of disbelief and bemusement in this respect. It really is a time capsule.
I couldn't agree more that people will seek, or sought, alternatives. I'm not going to assign responsibly between rocks and hard places - you have an unholy mix of government (represented by the
DfT» ), commercial operators (represented by First and MTR) and unions (RMT and ASLEF) - the only people powerless in there are the customers who chose to travel in other ways (or, rather, we forced to travel other ways because the otherwise-best option) wasn't running or couldn't be relied on.
I have to look back and ask "what was the final resolution" and
"why wasn't it possible to reach it in days not years". Low passenger numbers during the strikes may not have been the straw that broke the camel's back of the Bristol service, but they were certainly used in arguments to justify its demise.
