Striking when in a no strike job is a surefire way to find yourself unemployed
or even in prison shortly afterwards.

If you’ve sacked or put in prison all the qualified railwaymen, how are you
going run the trains in the months (or even years) until you’ve trained
some more?

You don't need to sack/imprison more than a handful, of course; just
enough to 'encourage the others'. Hence for example the original
definition of decimate.
