Earlier quoted context omitted.
Working in a union would be terrible. Can you imagine having to deal with seniority rules?
A union is whatever the members want it to be. Just because traditional unions operate a certain way does not mean a union for tech workers has to operate the same way.
Unions have all converged on operating the same way because the NLRA is very rigid, and over the decades, they've found a stable way of operating. Other operating structures have been tried over the last century, and all have failed except the current one.
If anybody believes that a tech union under the NLRA would break this trend, especially while presumably still being affiliated with other traditional unions, then the burden would be on them to explain why the forces that drive other unions would somehow not apply to tech.
