You are an input to the business, which is increased or decreased according to any number of factors, the least of which is a concern for "employee morale."
When this fact finally dawns on you, you are on your way to understanding corporations and indeed the world itself.
Well yes.
But the best way to deal with the reality is to know that it doesn't happen only to you but in masses.
When this happens, know that you came a long way and don't blame yourself.
Move on, focus on your famility and yourself and work towards new goals.
Don't let what happened affect your esteem.
