Well as a former railway man, on the Clerical side (TSSA) I was always able to avoid going on strike, although one time I was 'encouraged' not to cross the picket line. I went home, bu tthe move backfired on the strikers, as I wa son my way in to pay out the previous weeks wages, so they didn't get their wages. Hahaha, I really had a good laugh about that.
But from my experiencem strikes rarely achive the full and stated objective. Yes they might achieve a limited short term objective, but in the long term they only seem to be a lost cause.
I have seen strikes in both the rail industry, and after I left that, the strikes in the print industry, at the time of Wapping. All that the result was lost jobs and altered working practices. Both ASLEF & NGA are both lost casues now.
All this strike will do, is to inconveniance those who pay the wages of the strikers. They will use alternative means of getting to their destination and some of them will not return to using trains. While I accept that it is the right of every person to be legally able to withdraw their labour, at least think about the long term consiquensis.
