We therefore must really be wary of not falling into the ultra leftist illusion that 'all posties want to go all out to win all of the time and the union sold them out, again'.
It simply ISN'T true. Unions, are popular fronts in the workplace, representing all shades of political backgrounds and beliefs. Keeping them all happy is seriously difficult, and what is more, keeping them all, or most of them, ready and able to strike and rely on the union for reasonable judgement in disputes is even harder. This is not say that I am dismissing problems with bureaucracy, but to pretend that everyone is ready to 'all out strike till the revolution' is nonsense.
