I have not seen that. When a company gets bought out, usually the less senior employees go first!
The Temporary's go.
Then a severance package is issued, Senior personnel gets first choice.
Then it's position, they eliminated your position, so you work in another dept where you might not be at the top.
Then everyone goes except the warehouse forklift operators. they are packaging everything to go to Mexico.
When a company is purchased, I feel it is the Senior operators that should stay, yes they are "set in their ways" they have to be. It's called Company culture. Every company has a distinct culture, German, Japanese, Korean, etc.
When a company changes hands, you want Senior personnel on hand to train the new operators... unless they plan to kill the entire plant, usually those are "American Investors" that want a high ROI, greedy [censored].
