As it turns out (I just has cause to find this out but we’ll talk about all that some other time) labor conditions vary state to state because state labor law falls under states rights. So, I should have said “here in the at-will state within the US where I live and work, agreeing to binding arbitration is ordinarily a condition of employment.”
It could be worse, I could live in a right-to-work state where pay is generally lower and conditions worse because labor laws are even more slanted away from the worker and toward the employer.
ETA: Thanks for giving me hope things are better elsewhere
