Is there a pattern in layoffs

Employees who are top performers are laid off. Employees who are in a firm for a long time are laid off. Employees who are freshers are laid off. Employees from IIMs/IITs are laid off. Employees who work just to get the job done are laid off. Seniors are laid off. Juniors are laid off Hard working employees who get good ratings and give extra hours are laid off. Bad peforming ones are obviously laid off.

Is there anyone who is safe. It's just at the mercy of few decision makers at the top and no matter what you do you will never be safe.

Now I understand why parents say that government job is better.
