Same things happened in the UK. When I started in IBM Havant (S. England) in the 70's, it was the company to work for. Good salary, good benefits and a policy of non-redundancy. Over the years all that changed and by the 21st, Century, you were constantly looking over your shoulder and in my 50's (though working from the Portsmouth HQ) , I was a bit of a dinosaur. By that time, the Havant plant had been sold and under the name of Xyratex, was a disk file company. It enjoyed success for a while before going out of business and the buildings divided up between other companies.
Like others, I took a 'package' and on reflection, it was the best career move I made.
