I was planning to go on a Rover on June, much needed for my mental health after the last couple of mad years. The rail unions have now made that problematic, so thanks for that (not).
But it's quite simple, we live in a free market economy which, by the way, is by far the best way of maximising the efficiency of the economy, and, incidentally, raising the standards of living of everyone and paying huge amounts of tax for the NHS etc.
It is efficient because it directs capital and labour (mainly, but not exclusively, by means of higher or lower wages) towards their most efficient use.
How does that work ?
Like this :
Companies are experiencing difficulties recruiting train drivers (or any other workers) = increase the pay
Companies are experiencing no difficulties recruiting train drivers (or any other workers) = do not increase the pay
Result : labour ends up (by choice) where it is most needed, because, by definition, that's where the best pay is.
The RMT, or whatever they call themselves these days, are trying to bypass that by trying to grab more than they deserve by massively inconveniencing millions of people. Like me.
