Your argument makes no biz sense and is what is wrong with unions today.
Exactly. Unions used to be about improving worker conditions and safety. However, they long ago lost that focus. Today, the unions are about protecting bloated and inefficient contracts. Not to mention protecting unskilled workers who are unwilling to acquire new skills or training.
Instead of hiring the people most qualified (i.e. people with the needed language skills), the unions would rather hire people with no qualifications. Instead of basing career advancement on skill, it's based solely on how long you've been around....even if you do your job poorly.
It's no surprise the unions are dying.
