I would never have had you down as a meat packer, Annie.
I'm sorry you've had bad experiences with unions before. I've absolutely no experience whatsoever with unions in the US and, for that reason, i'd refrain from commenting on them. However, i would say that in my, negligible, experience trade unions have been rather helpful to have around.
I'm not one to go into details about personal bidness but, suffice to say, my mother was given top notch legal representation during her employment dispute, thanks to the trade union she belonged to, who secured a rather generous severance package accordingly. The same union also helps to inform other workers of their legal rights, facilitate educational and vocational opportunities, and encourage their members to make financial plans for their futures. (as well as the historic achievements of putting an end to child labour, campaigning for gender equality in the workplace, ensuring workplace safety and attempting to ensure the individual can stand up to the all powerful corporation.)
I dare say some unions are corrupt hives of depravity, and provide exciting film scripts. However, in a global sense, most unions are genuinely nice things, that smell of pine forests and make their members feel almost human, in a world of corporate bastards.
