It can sometimes be difficult to see beyond the small battles we fight all the time at work; these can lead to two attitudes.
One is to say, “Why are we banging on about socialism, we’re a trade union, what's that got to do with us?”. The opposite is, “what's the use? Even if we win this small battle and they'll just come back at us with something else.”
However, there is a very simple reason why these small battles are not only important, but expose the very nature of the system we live in.
