Former Employee complaining for Current Employees - Anonymous employee First Advantage Employee Review

I was let go last year, so wasn't in a rush to bash. But I've seen a few reviews from management, stating "change can be challenging" "if you can't adapt". How would one adapt, move to India? US employees are being told they're training their "support" or "backup" in India. So a team member trains their back up, within a month, they're gone, and your manager says "OK, now you need to train you're back up."
