There is also the point that most of the big battles have been won, now. The workplace is incredibly safer than it was 100 years ago. Workplace and wage laws are much more mature. There is welfare for the sick and the aged (to varying degrees depending on country). Apart from squabbling over the exact dollar rate for work, there isn't much in the way of big ticket items for unions to get solidarity over. My own personal experience with unions: 'I have a wage problem I need your help with' "You're only a part-time employee. We have to rate the full-time employees more, and we don't have the resources to help you, so no" 'But I pay the same as anyone else. There is no discount for being a part-timer' "(crickets)" So much for solidarity.
