It is like you telling me that you heard that some police officers did some horrible things somewhere so it is better to not have police at all.
Unions are run by majority rule, not by me. It is perfectly possible for the majority to implement rules that I disagree with.
The history of almost every union in existence, proves implementing barriers to entry is extremely common.
The fundamental reason, as for why unions try to screw over new comers is obvious. The reason is become people who aren't already in the industry don't get a vote.
It makes perfect sense as for why people who already have a job might want to screw over people who don't have a job, to prevent them from competing.
And it turns out that a lot of people are horrible individuals who want to discriminate against newcomers because "F you, they got theirs!".
> It is like you telling me that you heard that some
It is not some unions that do this. It is instead most of them.
Screwing over new comers to protect the established members is almost the entire purpose of unions.

Those people would be grandfathered in, if they already have a job, likely. The people who would get screwed are the ones in college right now, who aren't allowed yet to vote on union rules.
What I am instead saying is that I strongly oppose barriers to entry, that a union would implement, to keep out the highly qualified people from the top places like hack reactor.
It would not be possible for people like that to succeed if unions started throwing up barriers to entry, regardless of how good the bootcampers are.
And this applies to top tier self taught programmers too.
