Stop... Please please stop trying to rationalize layoff's. They are not just, they are not equal, they don't reflect you as an employee. Layoffs are performed to balance the books. There will always be collateral damage and they fully expect that. Humana generally employs people in a right to work state, this limits your ability to fight back.
The layoff is a tool used by the board to impress shareholders.... "look at us, we are cutting staff and will send you a few extra pennies on your EPS". This isn't about you, don't let it define you. You are better than this.
@vud+1ktHTBue is 100% right.
