Do amazon rehire employees that were once fired.

Yes, sometimes. Depending on the reason they were terminated.

They do rehire. Regualar associated have gotten rehired depending on what they got fired for. But they did change the policy for reapplying/rehire from 3 months to 1year.

I was rehired and am a regular associate

Very rarely do they rehire. I have only heard of management or office personnel being rehired if they were fired and that was only once, but never a regular associate.
