Unions don't block those features you want. All Labor benefits from group power against Capital. Your job today benefits from Union efforts in decades past.
edit: Fair points. I still believe that modern labor is a highly dynamical system. Many workers do need additional support and benefits, but our corner of the world is one of the best compensated and least regulated. Solutions for getting low-paid workers better equity shouldn't be used as a hammer -- workers earning six to seven figures do not need unions. Unions in tech will put downward pressure on our mobility, competitiveness, and compensation.
And we also have negative outcomes such as discounting worker education and experience (seniority should NEVER be valued over talent), restriction of work to narrow definitions leading to inefficiencies, the fact that the increased cost and decreased deficiencies hurt the product’s customers, and the list goes on and on.
We owe a debt to those who worked to get us simple humane things like taking children out of coalmines and getting benefits for working beyond 40 hours per week. Those days are gone. Now they fight to keep people who get drunk on the job or try to tell our factories that some people should stand around and do nothing because asking them to help move some parts from one room to another isn’t in their narrowly defined job description.
