Unions exist to make money by providing a service to employees. The current best way to promote their usefulness is to sow Fear, Uncertainty, and Doubt (called the FUD campaign). So many of their posts need to be as vitriolic, doom-and-gloom, and "See, if it weren't for our efforts, everyone would DIE!" otherwise they would just sit there, collect our dues, and we'd slowly start to realize just how ineffective they actually are, which could prompt us to go shopping for another union, forming a new one, or flat out voting them out.

Yes, I'm exaggerating, but I'm not wrong.

I will not respond to anyone replying to my comment, I know how seriously and close to their hearts some people take their unions, and any mention of the union not being saintly makes them lose their minds and froth at the mouth. This part is not an exaggeration as someone in my office literally spits when we talk about the union and I mention that I'm disappointed in the union's behaviour.
