My cousin was terminated from a Walmart for bad attendance, and he was told that they have a no rehire policy.... Ever. He waited 2 years and reapplied at a different location.. They wont hire him.
This would depend on why you were let go, if it was a lay off then that also depends, I think the best thing you can do to find out is to call them and talk to them. Hope this helps, good luck to you.
