I hear this argument against unionization all the time:
During those days the only thing a tech union would do would make your life balance better, but at the cost of your salary.
It feels like fear mongering when there are no data to back it up (this is not a knock against your post, it’s a complaint against the argument against unionization). I only know one person in a union and they have limited anecdotal data that shows that the cost of being in a union is offset by salary gains.
I’d take those last 5 bullets. I’ve worked hard to gain salary only to find that it didn’t matter. Every review I’ve ever had was a lie. If I was given a good raise, I was told that it was my hard work. If it was a bad raise, they found one item to give me ‘satisfactory’. A bunch of us shared our salaries over drinks one evening and we all were about the same. That was a big surprise to me.
Back to the point of the original article, employees talking is bad for employers. Unionization is one way to solve the collective agreement problem, but there are others. When employees (or any group for that matter) organize, they can make things happen.
