What it's like out there ( looking for work)

Why is job security so important?
I thought after the initial shock of not being able to return to a place u have been for 8 yrs! U say ok I'll go get a job tomorrow.. So u look nothing.... Apply nothing.... Bad reference? Who knows..... Meanwhile bills start collecting!! On and on till it's threatening life termination..... Then u find a job where u don't know how to act cuz u been at the same routine for 8 yrs.... Adjusting family adjusting life fell apart because of a idea of " I think they need to go" with a union in place it would not happen.. Think about it
