It's debatable whether they were stupid reasons, that's your opinion.
But yes, it's called Right to work.
> A Right To Work law guarantees that no person can be compelled, as a condition of employment, to join or not to join, nor to pay dues to a labor union.
This results in less powers to unions, which means employers have more freedom of discretion to fire employers, but also means employees are not forced into massive corrupt labor unions that halt efficiency.
Right to work states are mostly red states.
