I used to do employee-side employment law, once I had a non-Amazon picker client, he was getting jacked around for exercising his FMLA (Family and Medical Leave Act of 1993) rights, ultimately getting fired under the cover of a riff.
I did a lot of research about the 'picker industry' for that case. What a nightmare job. I can't imagine having to work somewhere like that with all the rules, quotas, bully leadership, favoritism, etc., worse than the Army.
