Razor, you ask a legitimate question. Here's your legitimate answer: it's called RETIREMENT! I am a senior citizen as are quite a percentage of my immediate colleagues. I made (with my wife) the decision that since I'm late 60s and already receiving my Western States pension, starting over somewhere else is a path we don't wish to go down. So I didn't. I will quite bluntly state that those around me considered my skillset to be far more valuable than my compensation.
On top of that, I know of a handful of similarly situated people in multiple locations who in addition to myself did indeed offer their services to facilitate cleaning out the system. We were absolutely ignored and pushed out the gate on July 30th, with over 30,000 shipments still in the system.
