[ELI5] Riot Games had a walkout today because of the company's stance on "forced arbitration". What is forced arbitration?

In cases where it's an employer and workers, forced arbitration means that if the workers think the employer did something wrong, they have to let a paid decision maker say who's right and who's wrong.  Then that's the end.  They can't get a second opinion, they have to take it and keep working or go away for good. 

The problem is that people have seen that these decision makers most always say the employer is right.   It doesn't look fair, or it really isn't fair.   This could be that decision makers get most of their business from employers and if the word gets around that they will tell the employer they're wrong,  other employers won't hire them. 

Employers know that they will likely win and tell workers that if they have a problem,  they must handle it their way or they can't have a job.
