If you fire people based on LOC just because it's convenient for you (the employer), the good employees won't come back. They'll take a better-paying job at a place that doesn't treat them as disposable or try to screw with their lives.
They are not any kind of prey. They are more thousand of white rabbit who are going to compete in the next few months to find job when all major Company in the industry are holding recruitment or even worse are also firing their own employee.
