I'm completely okay with underperforming software engineers getting fired. I don't want some system that I'm paying for with my union dues helping them maintain a job that they don't deserve. On the other hand, I've never seen a deserving and talented software engineer out of a job for very long. And if you're talented you will get paid much much more than average. The only software engineers that want or need a union are the ones that need artificial barriers to keep them employed.
